Frequently Asked Questions

Q: What chip does this RFID key tag use and is it compatible with standard 125KHz readers?

A: This key tag uses the T5577 chip, which operates at 125KHz and is broadly compatible with most standard 125KHz RFID readers and writers. It supports cloning and duplicating data from existing EM4100 and similar format cards, making it a versatile choice for access control and attendance systems.

Q: Can this RFID sticker tag be mounted on metal surfaces?

A: Yes! This tag features a built-in anti-metal interference layer in its construction, allowing it to function reliably even when placed on or near metallic surfaces — a common limitation of standard RFID stickers.

Q: How many times can the T5577 tag be rewritten, and how long will the data last?

A: The T5577 chip supports over 100,000 rewrite cycles and offers a data retention period of more than 10 years, making it a durable and long-lasting solution for ongoing access management needs.

Q: What is the read/write range of this RFID sticker?

A: The effective read and write distance is between 1 and 10cm, depending on your reader hardware and environmental conditions. This short-range communication is standard for 125KHz RFID and ensures secure, intentional scanning.
