This signal is modulated by the transmitting data according the register settings. The card responds with load modulation of the RF field. The resulting signal picked up by the antenna is coupled out from the antenna matching circuit and forwarded to the RX-pin. Inside the MF RC530 the receiver senses and demodulates the signal and processes it according to the register settings. Data is passed further on to the parallel interface where it is accessible by the -Controller. The MF RC530 uses a separate power supply for the driver stage.

For correct authentication of MIFARE Classic products the fast CRYPTO 1 stream cipher is available. The corresponding keys have to be programmed into the secure non-volatile key memory of the MF RC530. 4.1.2 SECOND PART OF CARD AUTHENTICATION Data to be transmitted to the card in this phase are generated automatically by the internal CRYPTO 1 unit inside the MF RC530. To request this action the according command has to be triggered. Only two commands need to be sent by application software to turn on CRYPTO 1 secured communication. 4.1.1 INITIATING CARD AUTHENTICATION The card will respond with the second message token. Then the communication status flags have to be checked by the -Controller. If authentication has been successful further communication with a MIFARE Classic card continues CRYPTO 1 enciphered. The correct key for the authentication has to be selected from the secure internal non-volatile key memory and loaded into the internal CRYPTO1 register. Next the authentication command is transmitted to the card.
