Far away from us? Test the actual use of NFC.

For a long time, when we mention NFC, there will always be a mindset-it is useless in China. Indeed, one major purpose of NFC is mobile payment, which is rare in China. Recently, China's high-end mobile phone Nubia z5 and idea mingyang dg90 have all added relatively rare NFC functions and provided corresponding NFC tags. On these mobile phones, what is the role of NFC? Does this mean that NFC will become the standard for mobile phones in the future?

First, let's take a look at the features of NFC (near field communication). As the name suggests, NFC is a short-range communication technology, which is different from our common Bluetooth and Wi-Fi technologies, it can only perform close-range communication. The NFC coil on the mobile phone is usually installed in the back shell or even directly into the battery. Therefore, NFC is usually triggered on the back of the mobile phone.

Although NFC is not widely used, many developers have created some special applications based on NFC features. The following is an experiment using NFC mobile phones and related applications.

Test environment:

Mobile Phone: HTC butterfly, Nubia z5, Samsung Galaxy Note II, Samsung Galaxy S III

Testing Software: nfcard, file master, NFC task Launcher

1. Induction IC Card

This is an application that uses mobile phone NFC to read Non-Contact IC cards. The common software is nfcard and mini-bus. Supports cards that comply with international standards such as iso7816-3/iso15693/Felicia and can be expanded to support specialized standards such as pboc2.0 in China ). This typeProgramIt can be used to read unencrypted balances, transaction records, electronic tags, and other information in e-wallets (mainly bus cards.

The following is an nfcard. You can use this software to view the balance and related transaction records of Shenzhen Tong (new version.

2. Transfer specific information

Transfer Application

The reason why the transfer here is quoted is that the Android mobile phone uses NFC to transfer apps, which is not the same as the transfer in general understanding. When the sender senses another mobile phone through NFC, the app information will be sent to the recipient, and the target mobile phone will immediately open the e-market and then download the relevant app.

There are also some extended functions:

1. Both parties have Sina Weibo. One of the mobile phones opens Weibo. when the other party receives the notification, the home page of the other party is immediately displayed.

2. Open the Google map. When the recipient senses it, a webpage is opened directly to display the current position of the sender.

3. The transfer contact is a more practical function. The sender can quickly receive the business card information from the receiver through NFC.

To share a webpage, the recipient opens the webpage tag that the sender is opening after sensing.

3. transfer files

This may be one of the most practical NFC functions we currently use. In the past, our two mobile phones directly transmitted files through Bluetooth or WiFi. The former requires a pairing process, which is a little cumbersome, while the transfer of files through NFC reduces this process, two mobile phones can directly transfer files. The Android device also has a new feature called Android beam, which is added after Android 4.0. It allows two devices with NFC to transmit photos, videos, and other media files.

In addition, using some third-party software, we can also conduct NFC pairs of conventional files to transfer files, such as file masters. Of course, the premise is that both mobile phones are equipped with this software to achieve relevant functions.

Using NFC to transfer files this Samsung has done a great job, and launched a new s beam feature at the release of Galaxy S3, which further accelerates the transmission speed based on Android beam, because it uses the WiFi function for transmission. However, this feature also has some limitations, that is, it can only be used on two Samsung mobile phones with the S beam function.

4. NFC tags

NFC tags are also a special feature of NFC at present. Previously, some mobile phones in LG and Sony will also attach NFC tags to their mobile phones through NFC tags, you can easily switch the scenario mode, call, and send text messages through induction.

This is the tag setting operation that Nubia z5 uses the built-in NFC tag function.

Other mobile phones with NFC can use third-party software to implement similar functions, and the functions will be improved.
