Topic: Reg:Writing ID to Mifare classic 1K card

Hi,
Good day to all!

I am using Mifare classic 1K card in one of my RFID based project for college.
I want to store register number of the student in the tag , so that the reader should read this number for authentication & link to his database in back-end PC .

I tried to change the ID of the Tag its not possible to change . reader will always reads the deafault ID (58C4E09C) .

How can I store the data in the  tag so that the reader  will read at the data ( register number )whatever i stored during authentication time.

Please help...
Regards,
Girish Kuamr

In that page you will find a link with complete specs of Mifare Classic 1K card.
You need it to understand that you cannot change ID of a tag and how to authenticate and read/write values.
