Because T5577 can support H ID. **Q: Will this wristband work on HID key fobs?** A: I couldn’t use them as they described never worked **Q: is it compatible with EM4100?** A: With the right programmer, you can write the 5byte EM4100 coded equivalent to this band. EM4100 standard is read-only but I assume you mean can this band support compatible codes, and the answer is yes. **Q: I have a safe lock, can I just program this to open the safe?** A: If your safe uses a rfid 125 khz lock them yes. Those locks would already come with a contact key fob or a chip card that you would use to open the safe lock. this braclet has the same chip as the key fobs. Normally these locks are found in gates and apartment buildings. ## Frequently Bought Together - YARONGTECH RFID Rewritable T5577 125khz Writable Silicone Wristband Black Adult Size (Pack of 5) - 125khz RFID Writable rewritable T5577 fob tag for RFID Writer (Pack of 10) (Black) - YARONGTECH 125khz RFID writable T5577 rewritable Silicone Black Wristbands (Pack of 2) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/66025363-yarongtech-rfid-rewritable-t5577-125khz-writable-silicone-wristband-black-adult](https://www.desertcart.hr/products/66025363-yarongtech-rfid-rewritable-t5577-125khz-writable-silicone-wristband-black-adult) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-15*
