Im planning to order a few to test , but only issue is I want to attach to the back of the cell** A: These tags are roughly the size of an American quarter. You can test the fit by placing a coin between your cellular phone and the case. If the quarter fits, you should be fine. If the coin doesn't fit, it is unlikely the tag will fit. By the by, I purchased these tags for use in a ring. I soaked the tag in fingernail polish remover to soften the PVC material, bent the tags to shape, and discovered the tag would hold the new shape once the PVC re-hardened. Hope this helps! **Q: Hi guys, does this card have t5577 chip or not?** A: yes,sure. it has T5577 Chip inside. Thanks. **Q: Does this work with Rosslare fob key's?** A: Yes **Q: What device is needed to write this tag? Will Keysys work?** A: No. Keysy will only work with Keysy tags/fobs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works with door locks *by G***. on 7 May 2026* As described works as it should ### ⭐⭐⭐⭐⭐ Flipper zero compatible. *by R**** on 7 November 2025* These are a great product, really slim and very robust.
