Bluetooth Wifi Module RFID Reader-writer

Bluetooth Wifi Module RFID Reader-writer

Apart from the function of ordinary RFID reader and writer, the bluetooth RFID reader and writer has the funcition of bluetooth wireless communication. It can communicate with the device with bluetooth function (such as bluetooth mobile phone, PDA, PC etc.).
The bluetooth interface of bluetooth RFID reader and writer provides security authentification function. The connected device must be authentified because only the authentified users can establish communication with it.
RFID reader and writer completely comply all opertation of ISO 15693 standard cards and also support reading card NO. of ISO 14443A/B type of card. It can complete the read and write operation to RFID card according to the user’s command and send the received data back to user device (such as bluetooth mobile phone). It can read message of card through press key. What’s more, this RFID reader and writer has built in RTC clock and FLASH. When do not connected with the user device, it can read directly by press key. The reader and writer will store the read message of card into FLASH and every record has the time of reading.
The user device can communicate with the RFID reader and writer via three ways: USB interface, bluetooth SPP service and bluetooth HID service. For bluetooth HID service, you can transfer the read card NO. to user device by the way of keyboard entry. The reader and writer can be configurated as automatical read card mode. When card is close to the reader and writer, it will automatically read the message of card NO.. If the reader and writer has already connected with user device this time, it will send card NO. to the user device directly.
