Frequently Asked Questions
Q: What does "UID Changeable" mean for these RFID tags?
A: "UID Changeable" means that Block 0 of the RFID chip — which normally stores the unique identifier (UID) permanently — can be overwritten on these tags. This allows you to program a custom UID or clone another card's UID, which is especially useful for access control testing and RFID development projects.
Q: Are these RFID tags compatible with standard 13.56MHz readers?
A: Yes. These tags operate at the standard 13.56MHz HF frequency, making them compatible with most NFC and RFID readers that support this frequency, including common ACR122U readers, PN532 modules, and many commercial access control systems.
Q: How many times can these tags be rewritten?
A: These RFID tags are rated for up to 100,000 erase and rewrite cycles, ensuring long-term reliability even with frequent reprogramming.
Q: What package sizes are available?
A: These tags are available in packs of 2pcs or 20pcs, so you can choose the quantity that best suits your project or business needs.
