FAQ
-
Q: What is the difference between CUID and regular UID (Magic Gen1)?
A: CUID is an upgraded version. Unlike Gen1 UID cards, CUID can rewrite Block 0 (Sector 0) multiple times without being easily detected by anti-clone systems (firewalls). It has a higher success rate for public transport or elevators that have anti-copy mechanisms . -
Q: How many times can I rewrite this key fob?
A: The writing/rewriting cycles are typically rated for more than 100,000 times, and the data retention is usually over 10 years under normal environmental conditions . -
Q: Do I need special hardware to write this key fob?
A: Yes, you need a 13.56MHz RFID reader/writer that supports UID/CUID writing (e.g., Proxmark3, ACR122U, or specific PN532 based devices). Standard commercial readers cannot write to the UID area . - Q: Can I get a free sample before placing a bulk order?
A: Yes, we provide free samples (you only need to pay for the shipping cost) for quality testing to ensure it works with your specific system
