K663/RDR module

K663/RDR module

Serial interface contactless 'smart' reader

The K663/RDR module is a ‘smart reader’ -the device combines a coupling device and an embedded application software-. If needed, you will find some more information about smart readers here.

The 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 K663/RDR module must be associated with an antenna from SpringCard’s portfolio or a custom-made antenna, depending on the project’s constraints (operating volume, size of the cards or tags to be processed).

Designed to be easily integrated, the K663/RDR requires only a single 3 to 5V power supply, and supports in-field firmware upgrade. Communication with host is made with a RX/TX serial link at TLL level (0-5V) and is CMOS-tolerant (0-3V). Thanks to the Low Power Card Detection (LPCD) mode, the K663/RDR can be used even in power-constrained systems.

The K663/RDR S version must be associated with balanced antennas. The K663/RDR A version must be associated with 50Ω unbalanced antennas.
