Tales of Things
Where everything has its memory
Bluetooth RFID Reader
This is a Bluetooth enabled RFID reader. The actual reader decodes 125 kHz EM4102 passive RFID tags and then transmits the tag id over the Bluetooth Serial Port Profile (SPP). In principle any device supporting Bluetooth SPP could connect to the Bluetooth RFID reader, and read tags as they are scanned.
