Rewritable NFC Stickers 20 pcs CUID Gen2 With Changeable UID Diameter 25 mm 13.56 MHz Memory 1 KB Transparent For Copies of Access Chips
You already have the maximum available quantity in your cart.
These self-adhesive NFC labels with CUID Gen2 chip allow for changing the UID identifier at will, as block 0 of this type of chip is not locked. They are suitable for creating a backup copy of an access chip or card that operates at a frequency of 13.56 MHz. The package contains 20 pieces of transparent round stickers, making them ideal for a small office, building manager, or for repeated write testing. The labels comply with ISO 14443 type A standard, so they are compatible with common 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 as MCT. iPhone does not support UID writing for these labels. The seller warns that NFC on phones can be less stable during writing, and for reliable reading and writing, a standalone RFID reader is recommended. The default card key is set to FFFFFFFFFFFF.

Before writing, ensure that your reader, writer, or application supports working with CUID cards. Stick the label onto a clean, dry, and smooth surface and make sure it is not folded or wrinkled 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 functionality of the label remains the same. It is advisable to note down which chip or card you have copied into the label for easy identification later.
The set of 20 transparent NFC stickers is suitable for users who regularly work with rewritable chips with changeable UID. The 1 KB memory and ISO 14443 type A standard ensure good compatibility with common readers and writers. Data on the label 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 fits almost anywhere. Thus, you have everything you need for backing up access chips, writing tests, and working with the MCT application all in one package.
