As a ‘smart' reader, the K663/RDR module, formats a number or an ID that is consistent with the host system's expectations. When the transaction involves a card with cryptographic security (Mifare Plus, Desfire), the module is also able to get authenticated (3DES or AES) and to read the data in an encrypted communication.
The module needs an antenna :
- either balanced
- or 50Ω unbalanced antenna.
It depends on your size constraints or the type of tag to support (see in our antennas portfolio or ask for a custom-made one).
The module only needs to be powered in 3 up to 5V and can be updated without being stripped down (firmware upgrade is available here). Communication with host is made with a RX/TX serial link at TTL level (0-5V), in compliance with CMOS (0-3V). Thanks to the Low Power Standby mode (LPCD), the host can sleep until the coupling device gives the information that a card is shown.
