@Holly… Good afternoon!
- “Task: Prototyping the RFID Reader and Tag”
“Open Example #2 – ChangeUID:
“Find this sketch under File > Examples > RC522 > ChangeUID.” <span style=”color: #ff0000;”>Typo; RC522 should be MFRC52</span>
2. Open Example #2 – ChangeUID: Followed instructions…. did not change the ID of either the FOB or the RFID card.
#define RST_PIN 5 // Configurable, see typical pin layout above
#define SS_PIN 53 // Configurable, see typical pin layout aboveMFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance
/* Set your new UID here! */
#define NEW_UID {0x1A, 0x2B, 0x3C, 0x4D} The picture above DOES NOT reflect this ID.CORRECTION!!!!
I was using the items in the RC522 packet. When I tried the items in the PROXMARK box… it worked.
Was this supposed to be this way?
Hi Leo,
Yes, unfortunately the RFID tags included with the RC522 are not capable of changing UID, we asked that you use the Proxmark RFID tags in the material sections of the task. The cards included with the Proxmark are equipped with the magic backdoor that allows for the changing of UIDs. This difference is demonstrated in the Proxmark section of the lab, only specific RFID tags versions can change. If you try to scan your card and you see that the error you have experienced, then it is a compatibility issue with RFID tags.
Apologizes for the late response,
David
