Do we need 4byte UID, Input parameter for Mifare Classic Authentication Command

[skumar1]

I am having issue in authentication the Mifare Classic 4K IC  MF1S70YYX_V1. I didn't get response for the command 0x60, 0x00,CRC(2bytes). I have read the datasheet, in the tables and diagrams this is the command structure, but in the description, it is mention that we need to give 4byte UID as input parameter to the Mifare Authenticate command.

Please clarify and confirm the required method to Authenticate successfully. 

I am using TRF7970A reader. I can read the UID. I have activated the card by successfully completing the anti-collision and Select as per the ISO14443 standard.  But after sending the Mifare classic authenticate command 0x60, 0x00,CRC(2bytes), the carrier frequency goes low, and I didn't get any response from the MF1S70YYX_V1 IC. Can you please let me know the possible reasons for this behavior?

Thanks and Regards,

Sunil
