Frequently Asked Questions
Q: Are these RFID keyfob tags compatible with my existing access control reader?
A: These keyfobs operate at 13.56MHz using the MIFARE Classic 1K (S50) standard, which is compatible with the vast majority of commercial access control readers and door entry systems that support this widely adopted protocol. Please confirm your reader supports 13.56MHz ISO 14443A before purchasing.
Q: Can I reprogram or change the UID on these keyfob tags?
A: No — these are fixed, read-only UID keyfobs. The 32-bit serial number is permanently set and cannot be altered. If your system requires a changeable or writable UID, you will need a different product type (UID writable tags).
Q: How many keyfobs come in a pack, and what is included?
A: Each order includes 100 individual RFID keyfob tags. Every keyfob comes with a key ring pre-attached, making them immediately ready for use or distribution to employees, residents, students, or other users.
Q: What is the read range of these RFID keyfobs?
A: The effective read/detection distance is between 3 and 10 cm. The exact range depends on the power and antenna quality of your RFID reader device.
