The Hunter Cat NFC is the latest security tool for contactless (Near Field Communication) used in access control, identification and bank cards. Specially created to identify NFC readers and sniffing tools, with this tool you can audit, read or .
If the UID is the card's serial number, then you can't change it. Mifare cards allow you to store about 1K of data on the card. You could easily have an address field on the card. An introduction to UID changeable cards, where to buy them and how to change UID using Arduino and MFRC522.

What happens?Learn to write to entire block 0 using PN532/Arduino. You have to send same commands shown in Part 4.
UID Changeable RFID Cards - Part 3, Write Entire Block 0. Finitepi Education. 1.06K subscribers. Subscribed. 110. 14K views 4 years ago. Learn to write to entire block 0 . No, the UID of genuine Type 1 tags (from Broadcom or, formerly, Innovision) cannot be changed. That UID is a serial number that is permanently burned-in into read-only memory during the manufacturing process.
Please kindly help me with RFID KIT mastering. I used standard demonstration software supplied with KIT Elegoo + Mega 2560. checked all attached mifare card and key. As result system only read card but when to change UID, send error. In an RFID access control system, each RFID card has a unique identifier (UID) that can be used to distinguish one card from another. In this particular Arduino project, the UID of the card is checked to grant or deny access. The chip ID code (also known as ‘chip UID, NUID,’ etc.) is 4–7 byte long preprogramed serial number. Some chip ID codes are programmed electronically, while others are even laser engraved during the chip manufacturing and cannot be altered or changed. The UID means chip’s Unique ID.To get the UID of your tag or your card, you need to upload the program 'DumpInfo.io', to find this file, go to the top menu of the Arduino IDE then click on File => Examples => MFRC522 => DumpInfo. This program returns the UID in hexadecimal.
