What kind of card did you run these codes on? Can you share schematic or circuit design related to the card.

Hi. I used 13.56 MHz RFID cards, but only for their IDs. There were no requirements to hold any other info on the card memory. The schematics are pretty simple -- and SPI connection of the MFRC522 module to the Arduino board.
