Do I Need NFC In My Smartphone?

NFC, as an abbreviation of Near Field Communication, is a kind of short-distance wireless communication technology that’s hot huge potential this year. Today were talking about NFC, what’s NFC function in our real phone, how to make use of it? Let’s have a look today.

What Is NFC?

Near Field Communication, NFC, it is called short-distance wireless communication as well, it allow data interchange between electronic devices such as smartphones, to exchange information from one spot to another in a non contact type situation (within 10 cm).

This technology is developed from Radio Frequency Identification(RFID) by scientist from Sony and Philips, it mainly services mobile, smartphone and other hand-held devices by providing M2M (Machine to Machine) communication. Due to NFC’s natural security, it has great potential and prospect in the mobile payment and other areas.

DO i need NFC In A Smartphone?

NFC has been widely used in smartphone applications, they are divided into five categories below:

  1. Touch and Go.

Access control management, bus tickets, entrance password. Use your phone as ticket identification or access control password to a card reading machine instead of using a login.

2.Touch and Pay.

So long as you close KINGZONE Z1 (with NFC function) to POS machine with NFC mode, payment can be submitted easily.

  1. Touch and Connect.

Connect two devices with NFC function, for instance, a smartphone and a laptop, Peer-to-Peer data interchange will be available, such as, download music, pictures and exchange phone books.

4.Touch and Explore.

User with NFC smartphone is able to glance over public transportation information by closing the device to public phone or poster with NFC function. This is an easy way for fast information access.

  1. Load and Touch.

People can receive or download information through GPRS network and apply it to payment or access control management. With one scan you can even send and automated text message in a specific format to the phone of housekeeper or to your smart home system and take control of his/her authority getting into different premises.

NFC Payment

We are now familiar with NFC payment, particularly after the promotion of several smartphone magnates like Samsung and Apple. Basically, mobile payment is a prime function of Near Field Communication.

After implanting NFC functionaliy in a smartphone, users can release their actual wallet or banking card and conveniently submit a payment in a mall or other entities, it is positive and nearly a future of payment because it has four natural advantages.

Advantages Of NFC Payment

  1. High security: NFC payment can be done within the range of 10cm only, it is a communication between one spot to another, hence, it has guaranteed privacy and security when making data interchange, for instance, entering your payment password.
  2. Convenience: Traditional wallets are redundant, you have to carry it wherever you go, but NFC payment doesn’t. You can gather all you banking cards together in one smartphone, it is easy to pay and extremely effort-less to take control of them.
  3. Low consumption: Its battery consumption nothing compared to Bluetooth or Wifi. In one way NFC communication only one device needs power.
  4. Low manufacturing cost: Now that NFC technology is developed the economy of scale has reached an affordable level and the whole manufacturing cost is stunningly low in 2015.

Disadvantages

1.It is early days, most countries and regions are just at a developing NFC payment tech, so, it is still awaiting official release. As such there is also a high user conversion cost as although manufacturing cost are low, the cost to you is high. To keep it simple, if you don’t have a phone with NFC, you cant use NFC, so there is this initial expense. The average user replaces their phone every 2 years and it is likely your next one will have NFC.

  1. After service. How many NFC after service available at this moment? None, at least at most regions and countries that only at the beginning of NFC payment.

NFC In Daily Life

Apart from payment, NFC has a bright future, even now you can get NFC stickers to open certain apps or put the phone in certain modes. You can put a sticker on your bedside table and when your phone is there it will automatically turn to silent mode, even put in the car for hands free mode to automatically setup and connect.

Let me share my experience,

1.First, you need an NFC sticker.

2.Open “Setting”, click “Network” column and “NFC”, the function is already initiated by default. If you want shut it down, press it again.

3.Put NFC sticker behind the phone and scan it.

4.After the notification “Label recorded successfully”,you can set the desired application or settings that will activate. For example, when bay the bedside table use Sleep Mode, you can make the phone in Flight Mode or silent mode.

5.After all settings are completed and saved, put the phone near the NFC sticker and it should open the set action automatically.

  1. If you want to end the experience, scan the sticker again.

The Difference Between Type C and USB 3.

If you are hooked into technology, then you have noticed changes in the USB world. Both Type C and USB 3.0 are mentioned on almost every new gadget and are being battered around by manufacturers but little explain the real tech behind these terms. This article will explain exactly what the differences are.

 Type C is a plug; USB 3.0 is a protocol.

USB-Type-C-41

The Type C Connector

We’ve all seen the UBS Type-A, the original USB. Type B, is a square port that is used in printers. Micro B is used in many small devices. Type-C is the new plug I the market. It is small and compact. This connection is used in place of type A and type B ports. This connection can run on many protocols and older specs like USB 2.0. It measures 8.4mm by 2.6mm. This means that it requires only a little space on the circuit board. It can, therefore, be used also on Smart Phones. It is reversible making it easy to plug upside down. This port is not compatible with any other port but it does not need to be, Type C was designed to be the one cable for everything. Small enough for your phone but powerful enough to power your laptop.

All those extra pins open the connector up to hosting almost every type of connection you would ever need, the spec can;

  • Transfer files and connect devices just like a regular USB.
  • Charge high power devices even laptops.
  • Stream video like HDMI.
  • Stream audio.
  • Do all of the above at the same time.
  • Can be converted back to regular USB with either an adapter or Type A to Type C connector.

Type C is something you should look out for in your next device as it is expected to replace the older USB plugs and eventually all you will need are Type C connections.

USB 3

Unlike Type C that is a physical connector, this is a protocol that supports 5 gig bits per second. It is faster than USB 2.0 and can be amazingly fast if used with external SSD enclosures or pen drives.

Both go hand in hand

The USB 3.1,3 and 2 specification is supported in the Type C system and ensures all your old devices will be operational in the future.

It will be a while for these two specs to become dominant, but looking at everything that has been released already this year, it wont be long until the one cable for all idea is fully embraced.

All you Need to Know About QC4.0+

Last year, Qualcomm Technologies released QC4.0, the most advanced charging technology that is likely to change the charging ability of future Smartphones. At the same time, the company also released the Snapdragon 835 processor which they say will be the next generation Smartphone processor. At the moment, there is no device that supports Quick Charge 4.   The company revealed that their advanced charging technology will be available with the Qualcomm Snapdragon 835 processor.

QC4.0+ benefits

What are the benefits of Qualcomm Quick Charge 4?  Basically, QC4.0+ charges up to 15 % faster compared to previous releases. This latest technology will be also 30 % more efficient and will run up to 5-degree Celsius cooler compared to previous releases.

For instance, five minutes of charging will guarantee you more than 5 hours of battery life. Your Smartphone’s battery will attain 50 % of charge in less than 15 minutes of charging. This means that future Smartphones with Qualcomm Quick Charge 4 will charge like they are connected to two high-powered chargers. Their batteries will have increased efficiency and the Smartphone themselves will stay cooler.

Key features of QC4.0+ and how they work

Quick Charge 4 has a wide range of advanced features compared to prior releases. Here are the key features and how they work.

Battery Saver

This feature was included in this latest generation not only to provide comprehensive safety while charging but also to extend the battery’s charging cycle life. A protection feature is implemented at various stages of charging in order to keep accurate records of temperature, current, and voltage while protecting various components of the Smartphone such as connectors, cables, systems and the battery itself.

USB Power Delivery and USB Type-C

The two technologies were incorporated in QC4 adapters to ensure that there is consistent charging performance. These technologies will also ensure that one accessory supports a variety of mobile devices and charging implementations.

Intelligent Negotiation for Optimum Voltage (INOV)

Quick Charge 4 is incorporated with this latest algorithm to help your Smartphone determine the amount of power to request at a particular point. This not only maximizes charging efficiency but also enhances optimum power transfer.

Dual Charge

A second power management IC is also incorporated in Quick Charge 4. Charging your Smartphone using two power management ICs has many benefits. For instance, the charge current is divided into two which reduces charging time and promotes more efficient thermal dissipation.

3 easy ways to transfer everything to a new phone

Having a new phone is delightful but transferring data can be an initial hurdle. Here are 3 ways to transfer the data from your old phone to your new phone.

By Google Account

Backing-up and restoring data by Google account might be the method most people know. Supported by the backing-up and restoring of an Android system, users can transfer their data including Google Calendar, WiFi account and password, desktop setting, Gmail, screen settings, language setting and some of the apps. It is by far the easiest way to replicate your basic system data.

The exact path is entered into the “setting>back up and restore”, unlock the backup set and choose a Google account.

As to the new phone, when you log in the account you have chosen in the former step, you will find everything will be restored as you choose. As this method uses the internet, the time to setup your new phone will depend on the internet connection speed.

In-house solutions

If you buy the same brand as your old phone, there is an effective way most people ignore, many brands themselves have a backup/restore tool for transferring data to new phones. Check your phone settings or jump onto Google to see if an app is available. :

Here are some data apps:

This method can save time if you have a large amount of data as you do not require the internet to copy the data across to other devices.

Tap & Go: A New function of Android

Android’s Tap & Go service arrived with the Android 5.0 Lolipop system launched a few years ago.

You can transmit data (including apps and apps data) through the NFC and Bluetooth. This method will work if both devices have NFC and Bluetooth.

Transferring apps to your new phone with tap and go

  • When you turn on your new phone, please unlock your old phone and open NFC. Put these 2 phones back to back.
  • You will receive the notice of adding a new account on your old phone.
  • When the screen on your old device says,”Copy accounts and data from this device?” tap “ok”.
  • Enter your Google account and password, then set your new phone as a new device and the transfer will start.

The key advantage to this method is you can choose what apps you want to copy so it is ideal if you are wanting to leave some older or unused apps behind.

Most Common Repairs on Laptop Displays

When it comes to laptop repair, displays are some of the least likely components to fail. Nevertheless, problems can arise that require replacement or repair of the parts that make up the laptop display and its connection to the system board and other components. Here is a list of some of the most common repairs pertaining to laptop displays.

  1. Loose connection

The cable that connects the display to the system board is generally a very thin one, with a small connector. If this connector becomes loose, it may cause the display to go black intermittently or to fail to work at all. Luckily, fixing this problem is generally as easy as reseating the connector so that it functions properly, although it can be difficult to access on some models.

  1. Bad inverter

The LCD inverter is responsible for providing power to the backlight of the display. When an inverter is malfunctioning, it can cause the screen to go black, the brightness to dim, and other issues. You can find replacement inverters by finding individual sections on our website, such as IBM Lenovo laptop inverters.

  1. Bad backlight

Backlight problems generally cause the same problems as a bad inverter, making it difficult to diagnose between the two issues. In many cases, it can be a good idea to replace the inverter first and see if it solves the problem.

  1. Bad display/bad pixels/stuck pixels

The other common display problems lie in the LCD screen itself. Issues such as stuck pixels, bad pixels, and lines or dots on the screen can usually only be resolved by replacing the screen itself. You can find replacement screens on our website under the correct manufacturer heading for your laptop, such as Toshiba Laptop LCDs.

This list gives a general breakdown of the most common laptop repairs. If your laptop display is having other problems, or you are inexperienced in laptop repair, it is a good idea to have a professional repair shop diagnose and repair your laptop. Feel free come to our on-line shop to find whatever parts you may need to fix your display.

How To Troubleshoot A Laptop Inverter Issue

In a laptop, the inverter refers to a small circuit board housed as close to the monitor lamps as possible. An LCD typically requires two monitor lamps to illuminate your display, and those lamps require a higher voltage than the rest of your machine. The inverter powers these bulbs to increase the brightness of your display to a crisp, visible level.

When the inverter in a laptop goes bad, this can cause multiple problems with your machine. It can cause your screen to flicker on and off, become too faint to read, or even cause a faint buzzing noise. To test whether your inverter in your laptop has in fact gone bad, you will need to do one of two things: either replace the inverter board with one you know to be functional, or connect a backlight lamp you know to be functional. If the inverter board works or if the good backlight does not work, you know your original inverter board has gone bad. In most cases testing a good backlight will be easier, as most backlights are universal and will work as long as the connectors match those on your inverter board. To access either of these components, remove your screen bezel in accordance with your manufacturer’s instructions. Once removed, you will see the inverter board beneath your screen. The left side connects to the LCD cable, while the right connects to your backlight. Be sure when installing or removing any components of your machine that you have removed the AC adapter and battery from your machine to prevent shortage or electric shock.

Additionally, if you have a multi-meter you can attach it to the inverter cable connection on the motherboard itself to check that your inverter is receiving power. If you don’t, switching the inverter board or backlight will yield similar results. In some cases, your laptop will have a lid closed switch. If your model does have one, check to make sure that it is not sticking by tapping it repeatedly. If this changes the display of your monitor, your inverter may be fine; however that switch may be cutting off power to your display.

Laptop inverters are specific to each machine and not interchangeable. To replace your inverter, you will need to find the specific part number, which can usually be found in your user manual, or by contacting the manufacturer. For some companies, you can look up the information for your machine and its individual parts online as well. Inverters are generally easy to find at any laptop parts retailer.

Why Does AC Adapter Polarity Matter?

The AC adapter is an important component of any laptop. Without it, it would not be possible to recharge the laptop’s battery, which is essential for portability. The AC adapter also makes it possible to use the laptop without draining battery life, helping extend battery life on long days. Laptop AC adapters are not all created the same, however, and one of the distinguishing characteristics of different AC adapter designs is their polarity.

The polarity of an AC adapter refers to the way that power flows through the cable and into the laptop itself. The power coming from a wall outlet is what is known as alternating current (or AC power), but the power needed by the laptop is known as direct current (or DC power). The AC adapter converts the AC power into DC power at the correct voltage for the laptop.

The polarity of the adapter happens in the connector that is inserted into the laptop directly. The connector is comprised of a tip and a barrel. The tip is essentially the hole in the middle of the connector and the barrel is the larger area surrounding this hole. Power can only flow in one direction, either from the tip to the barrel or from the barrel to the tip. This is what is meant by polarity.

An adapter with a positive polarity means that its tip is positive and its barrel is negative. An adapter with a negative polarity means that its tip is negative and its barrel is positive. There is no standard design, so adapters and devices are often marked with a symbol to show their polarity. The side connected to the center dot is the tip, and the side connected to the symbol shaped like a C is the barrel.

It is important not to plug an adapter with the wrong polarity into a device. It will not supply power, and in some cases can cause damage to the device or the adapter. Visit Spareparts Warehouse to find a compatible adapter for your laptop, or view specific sections, such as Sony Laptop AC Adapters and Toshiba Laptop AC Adapters to find adapters specific to your laptop’s manufacturer.

AMD Ryzen Threadripper: Everything we know so far about this monster CPU

AMD’s Ryzen Threadripper chips could very well be the most powerful consumer CPU ever introduced when it releases in August. With up to 16 cores and 32 threads, Threadripper gives the high-performance Intel products currently dominating high-end desktops something to worry.

The specs we know

  • The Ryzen Threadripper 1950X ($999 on Amazon) features 16 cores with simultaneous multi-threading (SMT) for 32 threads of compute power. The base clock speed of the chip is 3.4GHz, with a 4GHz boost speed.
  • The Ryzen Threadripper 1920X ($799 on Amazon) will feature 12 cores with SMT for 24 threads of compute power. The base clock speed of the chip is 3.5GHz with a 4GHz boost speed.
  • The Ryzen Threadripper 1900X will feature 8 cores with SMT for 16 threads of compute power, similar to the Ryzen 7 1800X but slotting into more capable X399 motherboards. The 1900X’s base clock speed is 3.8GHz with a 4GHz boost speed.
  • All Threadripper chips pack a whopping 64 PCI-E lanes
  • Memory: Quad-channel DDR4
  • Platform: X399 with a new TR4 socket that is incompatible with existing Ryzen chips.
  • All chips are unlocked for overclocking adventures.
  • Can’t be “delided” easily as it uses a solder thermal interface material.
  • Release date: Threadripper PCs will be available for sale on July 27. The Threadripper 1950X and 1920X CPUs will launch on August 10, with the 1900X releasing on August 31.
  • Alienware has the worldwide exclusive on Threadripper systems among large PC manufacturers, but many U.S. boutique builders will offer it as well.
  • Both parts will be 180 watt TDP chips.
  • Ryzen Threadripper CPUs will support up to 1TB of RAM when 128GB LR-DIMMs are used.
  • Threadripper will not ship with an included liquid-cooled cooler as has been rumored. It will include a bracket adapter that works with most liquid coolers.

It will support up to 1TB of RAM

No, we’re not kidding. Threadripper shows its server roots and will be able to support up to 1TB of RAM if you populate all 8-DIMM slots with 128GB LR-DIMMs or Load Reduced DIMMs. Unlike today’s Registered DIMMs that use a chip to redrive some of the signals to the memory directly from the CPU an LR-DIMM uses a memory buffer to re-drive all of the data and instruction sets.

None of this comes cheap though. A single 32GB LR-DIMM  DDR4/2133 module costs $1,100, so you can imagine how much a 128GB LR-DIMM will cost when available.

And yup, if you guessed, the typical person doesn’t need 1TB of RAM, but in the “look what I could if I wanted to category,” it’s a major bragging point.

This factoid was actually noticed by Anandtech in a video Alienware published last month.

Best ultrabook laptop of 2017

Dell might be sticking to the adage of “If it ain’t broke, don’t fix it” when it comes to the XPS 13, but that strategy keeps producing the best ultrabook of the bunch. The Kaby Lake XPS 13 shares the same design as its predecessors: a quality aluminium exterior and carbon-fiber top, and that wonderfully compact, bezel-free 13-inch screen.

Dell actually released two updates to the XPS 13 in 2016: The one at the start of the year swapped in a Skylake CPU, added a USB Type-C port that served as an alternative charging port, and offered upgraded storage options. The most recent refresh—and our new pick for Best Ultrabook—keeps the same chassis changes as the Skylake XPS 13, features a jump to Intel’s new Kaby Lake processor, and sports a slightly larger battery. You get improved performance across the board, with a nice bump of an extra half-hour of battery life during video playback.

Kaby Lake戴尔XPS 13

The Kaby Lake version of the Dell XPS 13 maintains that balance between portability, compact size, and performance that we like so much.

Our only lingering complaint is the small keyboard, but overall, you can’t lose with the newest XPS 13. It’s a truly compact ultrabook that punches out of its class.

Runner-up

If looks are more your thing, the HP Spectre 13.3 certainly has a distinct profile: It’s one of the thinnest ultrabooks around. For anyone coveting the streamlined experience of Apple’s 12-inch MacBook, this 13-inch notebook will bring you close while providing superior performance.

You might expect such a skinny laptop to sport a lower-wattage Core i3 or i5 processor, but HP fits a 15 watt Core i5 or i7 processor into this Spectre. That puts it on par with other, chunkier top-tier ultrabooks, like the XPS 13. Combined with its 256GB M.2 SSD, it runs smoothly and swiftly during typical office drone work (word processing, spreadsheet editing, web browsing, etc), without any heavy throttling of performance during CPU-intensive tasks. HP also made the ports count: While there are just a few, you get not one but two Thunderbolt 3 ports, as well as a USB-C port.

hp幽灵13.3

The HP Spectre 13.3 is one of the sleekest ultrabooks around.

The drawbacks of this modern and sleek notebook are its battery life, which is modest due to its smaller battery, and its wider frame. (The Spectre 13.3’s hardware and cooling configuration requires a certain amount of space—HP’s engineering is impressive but can’t defy the laws of physics.) It’s for those reasons that we prefer the Dell XPS 13, but this laptop is still a very fine companion.
