MFRC630 Authentication Mifare 7UID

shybora — Mon, 04 Nov 2019 06:39:12 GMT

I used MFRC630 chip

i succeeded mifare classic 4UID card Authentication.

But Now happens error in mifare classic 7UID.

MFAuthent Command is consisted of 60h or 61h, (block address), (card serial number byte0),(card serial number byte1), (card serial number byte2),(card serial number byte3);

in this case 7UID , I wonder if it's right to use card serial number 4

What are the actions required for Authentication ?

Dear hwang bora,

Hope you are doing great, the anti collision procedure for 7 byte UID cards is the same just by adding a second cascade level as explained in ISO 14443-3 figure 10. also you can use the NFC reader library as a reference to your implementation NFC Reader Library | NXP.

Hope this information helps.

if you have more questions please let me know.

Have a great day !

Jonathan

Can you share your code, I have a problem in granting MFRC630 authorization?
