NTAG® 213 Compatible Direct Write UID

INTRODUCTION

Need to make perfect clones of NTAG® 213 cards and tags ? Our UID Modifiable "Magic" NTAG® 213 Compatible Direct Write tags are what you need.

Hands on: See the card in action

The NTAG® 213 Compatible Direct Write UID Modifiable can be used with several tools:

LibNFC - change UID

To change the UID of your NTAG® 213 Compatible DirectWrite UID Modifiable tag with LibNFC, write a full tag dump to the tag, with the UID and BCC set appropriately. Do not use the nfc-mfsetuid tool to change the UID. This tool is built for MIFARE Classic® Chipsets, not NTAG® 213 Chipsets - using the tool will permanently brick your tag.

nfc-mfultralight w /tmp/nfc.dmp --full   # Replace nfc.dmp with your FULL dump

Proxmark / iCopy-X

hf mfu setuid –uid 11223344556677   # Replace 11223344556677 with the UID

LibNFC - Live Demonstration

Please note: The following example mentions an "Ultralight" tag, but the process is identical for NTAGs

Unbricking

"Soft-bricking" refers to when a magic card has been configured in a way that prevents it from being detected. Ways of soft-bricking tags include:

• Incorrect BCC
• Incorrect SAK
• Incorrect ATQA
• Incorrect ATS
• Incorrect ACL (Access Control) Values

Some "soft-brick" situations can be resolved with special commands. If your NTAG® 213 Compatible UID Modifiable is "soft-bricked", you can try recovering it with the following methods:

Via external reader/writer and MTOOLS

Select the "UID Changer" function in MTools, select "bricked" and run the task

IMPORTANT:

Lab401 cannot provide refunds under any circumstances for cards that were 'bricked' due to incorrect configurations.
