Overview
Self-Adhesive NFC Labels CUID 5 pcs Changeable UID and Block 0 Rectangular 13 x 28 mm Chip S50 1K 13.56 MHz For Copying Access Chip

Self-adhesive NFC labels with CUID chip function just like standard S50 1K IC cards, but they also allow you to rewrite block 0, where the serial number or UID is stored. This means you can upload any identifier to them and create a backup copy of your access chip or card. The pack contains 5 rectangular labels measuring 13 x 28 mm, which is a practical amount for testing or for backing up several chips at home. The labels operate at a frequency of 13.56 MHz and comply with ISO 14443 type A protocol. The thin wet inlay design easily adheres to a card, pendant, or other smooth surface.

Each label consists of a thin self-adhesive PE film, within which the antenna with the chip is visible, and the labels are affixed to a white backing strip. The chip memory has a capacity of 1 KB EEPROM and data can be rewritten up to 100,000 times. Changing the UID can be done with an Android phone using the Mifare Classic Tools app, known as MCT, as well as devices supporting CUID cards, such as ACR122U, Proxmark 3, PM5, 300CD, X100, or iCopy 3, 5, and 8. The seller warns that standard RFID copiers and writers cannot write to CUID cards at 13.56 MHz. The default key for the card is FFFFFFFFFFFF.

Before writing, ensure that your reader, writer, or app with CUID cards is functioning properly. Stick the label onto a clean, dry, and smooth surface and do not reposition or press it down while applying to avoid damaging the antenna inside. The reading range depends on the reader, so it is advisable to hold the label as close as possible during reading. You can note on each label or its backing which chip you copied into it, so you can easily identify the labels later.

The set of 5 rectangular NFC labels is suitable for anyone who needs just a few rewriteable chips with changeable UID. Compatibility with the S50 1K standard and ISO 14443 type A protocol ensures cooperation with standard card readers. You can rewrite the data up to 100,000 times, allowing you to reuse one label for different chips. The thin self-adhesive design is unobtrusive and fits almost anywhere. For backing up your access chip, testing writing, and working with the MCT app, you have everything you need in one small package.
