NFC technology is hailed as the next generation technology with significant impact

NFC technology is hailed as a next-generation technology with significant impact, while the impact has not yet been achieved, the big Smart flagship has gradually joined in supporting it, developing a variety of fancy features, ranging from touching to exchanging business cards to NFC payments, what kind of technology is NFC? Let's get to know it step-by-step.

What is NFC?

NFC is all called the Near Field Communications (Near-field communication), which is the technical standard for wireless communication between mobile devices by proximity to each other. Different devices have different maximum transmission distances, generally less than 10 cm.

The theoretical transfer rate of NFC is 424 kbit, slower than Bluetooth 4.0. The advantage of its relative Bluetooth is that it consumes less power, does not require tedious pairing, and has a fast connection, usually in just one-tenth seconds.

Although NFC is more power-saving than Bluetooth 4.0 when transferring data between two running devices, it consumes more power than the Bluetooth 4.0 low-power version (not typical Bluetooth 4.0) when interacting with devices that are not running (such as a shutdown smartphone or a NFC-enabled label).

NFC features developed on Android

The 2010 Samsung Nexus S was the first NFC-enabled Android device to be released with Android 4.0.

Android Beam

Android Beam is the Android 4.0 feature that uses NFC to pair two devices and then transmits data via Bluetooth. This approach also leverages the fast speed of Bluetooth and the instant pairing advantage of NFC.

S-beam

S-beam is a unique NFC feature for Samsung handsets and is released with the Galaxy S3, adding support for video and picture transmissions. S-beam also uses NFC to pair devices, but sends data with Wi-Fi direct connection.

Using Wi-Fi instead of Bluetooth for transmission can significantly increase the transmission rate. Android Beam supports all Android devices with NFC and Bluetooth capabilities, while S-beam only supports Samsung's high-end devices.

NFC Use payment system

One of the most anticipated uses of NFC is the contactless payment system, which is similar to a credit card, allowing users to have mobile wallets. Because NFC can be encrypted, it is safe to pay in this way.

Google Wallet allows users to store debit cards, credit cards, coupons and gift cards, use NFC for secure payment, and simply touch the NFC-enabled device and PayPass terminal. But the current Google Wallet is available only in the United States.

Connection and pairing

One of the big advantages of NFC is simple and fast pairing, and advertising often describes NFC as "touch or even", which is no exaggeration. Some producers have used this advantage to match the pairing of Bluetooth headsets, Mike and other devices and NFC devices.

Some games allow users to quickly pair for multiplayer games.

Send and receive large files

The Android beam supports sending pictures and videos to large files, and can also quickly share contacts, such as quick sharing of business cards.

NFC Tags and stickers

New NFC tags and stickers allow you to set up different tasks by using the appropriate app. By gently touching, users can change their phone settings, send text messages, open an app, or implement other functions. For example, a user can put an NFC tag on his bedside bed and can set the alarm clock or turn on the vibration mode if he touches it before bedtime.

Summary

NFC is far from reaching its potential. This is because some companies and users have doubts about new technologies and security concerns. Google has developed Google wallets using NFC, and other companies have developed their own payment systems to compete with Google, such as ISIS, the Verizon, At&t and T.

Obviously NFC has great potential and there are already a lot of Android handsets that support NFC, so the prospects are great.
