National Technology launches Bluetooth RFID mobile phone adapter reader

National Technology recently launched a Bluetooth RFID mobile phone adapter reader. The device has anti-counterfeiting, logistics information collection, input and other functions. It reads passive UHF_RFID tags, obtains various information of the corresponding products, and transmits the collected information to the mobile phone through the Bluetooth protocol, which enables the mobile phone to remotely verify or store through the mobile network. The reader works in the 860MHz~960 MHz frequency band, has a built-in lithium battery, and can read about 500 times after each charge. It can be applied to anti-counterfeiting and traceability of food, tobacco, alcohol, medicine, electronic products, brand clothing and other scenarios.

　　The usage process is as follows:

　　The device has an external size of 80*45*15mm and is equipped with red and green indicator lights, which respectively indicate power and information feedback. It also has SDK support, providing supporting Bluetooth interface standards for secondary development (free) and supporting Android application development (charged).

　　The process of installing the application on the device is very simple. First, the reader device should be turned on. If the Android phone does not have the application software installed, turn on Bluetooth and search for new devices. If a device named "RFID" is found on Bluetooth, the user will initiate pairing and the connection will be automatically established.

Reading information process

　　Open the application software, as shown in the figure:

　　Figure 1 Main interface of the application

　　Click on the information to read, and the interface switches to Figure 2:

　　At this stage, the application software actively searches for currently available Bluetooth devices. If the number of devices with the device name "RFID" is 1, the device will be automatically paired. During the pairing process, the user will not be prompted to enter the PIN code (the default is 1234), which will be automatically entered by the application software.

　　If the number of devices with the device name "RFID" found is greater than 1, the available device names and device MAC addresses will be displayed for the user to choose. After the user selects the device, the application software will actively pair with the device and automatically enter the pin code (the default is 1234).

　　After the pairing is successful, the indicator light of the Bluetooth reader will flash. At the same time, the application software will actively initiate the connection. After the connection is successful, the mobile phone will display the following content.

　　After receiving the file, the application software enters the interface shown in Figure 3:

　　Figure 3 Display file information

　　Display the received information on the interface.

　　If the user clicks "Online Query" (this function needs to be customized), the manufacturer's database can be queried through the Internet.
