Self-adhesive NFC Stickers 50 pcs CUID Gen2 with Changeable UID and Block 0 Round 25 mm 13.56 MHz Memory 1 KB Transparent for Services and Companies
You already have the maximum available quantity in your cart.
These self-adhesive NFC tags with CUID Gen2 chip allow for the arbitrary changing of the UID identifier, as Block 0 of this chip type is not locked. They are therefore suitable for creating a backup copy of an access chip or card that operates at a frequency of 13.56 MHz. The packaging contains 50 pieces of transparent round stickers, making them sufficient for services, building managers, and companies that manage dozens of access chips. The tags comply with the ISO 14443 Type A standard, so they are compatible with standard IC card readers and writers. You can stick the label onto a plastic card, key fob, phone case, or any other smooth surface.
Each sticker has a round shape with a diameter of 25 mm and the antenna with the chip is clearly visible inside the transparent inlay. Block 0 can be rewritten directly using a standard IC card reader and writer. On Android phones, changing the UID is also possible via the Mifare Classic Tools app, known by the abbreviation MCT. The iPhone does not support UID writing for these tags. The seller warns that NFC in phones can be less stable during writing, and therefore recommends a separate RFID reader for reliable reading and writing. The default card key is set to FFFFFFFFFFFF.

Before writing, please ensure that your reader, writer, or application supports working with CUID cards. Stick the label onto a clean, dry, and smooth surface and take care not to overlap or crumple it during application, as this could damage the antenna inside. Depending on the production batch, the shape of the coil in the sticker may vary slightly, but the function of the tag remains the same. It is advisable to note on the sticker which chip or card you have copied into it, so you can easily identify them later.
The set of 50 transparent NFC stickers is suitable for those who regularly copy access chips and want to have rewritable labels with changeable UID always at hand. The 1 KB memory and ISO 14443 Type A standard ensure good compatibility with standard readers and writers. Data on the sticker can be rewritten up to 100,000 times, allowing the same sticker to be reused for different chips. The thin self-adhesive design is discreet and can fit almost anywhere. Thus, you have everything you need in one package for backing up access chips, testing writing, and working with the MCT app.
