Near Field communication (NFC) is a popular technology in recent years, and is becoming a set of standards for smart phones and similar devices to establish radio with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. The RFR811 is a host-linked contactless card reader developed based on 13.56 MHz Contactless (RFID) Technology. Compliant with the ISO/IEC18092 standard for Near Field Communication (NFC), it supports MIFARE®, ISO 14443 A and B, ISO15693 and FeliCa cards. The RFR811 is ideal for both secure personal identity veri cation and online micro-payment transactions. Other applications include access control, e-payment, e-ticketing The RFR811 comes with an optional holder with it could mount the reader either on desk or wall, so that users can tap contactless cards or NFC-enabled devices onto the RFR811 with ease.

When the scanner is the master device and cradle is the salve, while scanner goes to sleep mode, the cradle is always on for waiting the master device, to re-establish the connection is controlled by the master, hence press a trigger of the scanner will re-establish the connection
When you connect the scanner with PC, the scanner is set to Slave mode and the PC is the master, when BT disconnect you have to establish the connection from PC, since PC is the master device, it will search the slave device, and the slave device is listening.
