Frequently Asked Questions
Q: What RFID chip types are compatible with these blank 125KHz RFID cards?
A: These cards use T5577 and EM4305 chips, two of the most widely supported rewritable 125KHz chip standards. They are compatible with most 125KHz RFID readers, writers, and access control systems that support these protocols, including many common proximity door entry and time-attendance systems.
Q: How many times can these RFID cards be rewritten or reprogrammed?
A: T5577 and EM4305 chips support a very high number of write cycles (typically up to 100,000 or more), making them well suited for repeated programming, testing, and cloning tasks without significant degradation in performance.
Q: Do I need special equipment to program these blank RFID cards?
A: Yes, you will need a compatible 125KHz RFID card reader/writer or duplicator (sold separately) to program these cards. Many affordable handheld RFID copiers available on the market support T5577 and EM4305 chips. Simply place the card on the device and follow the programmer's instructions to clone or write new data.
Q: What size are these RFID cards, and will they fit in standard card holders?
A: Each card measures 8.5 × 5.3 cm, which is the standard CR80 credit card size. They will fit in the vast majority of standard card holders, badge holders, and lanyards without any modification.
