## Questions & Answers

**Q: Hi , can the tags work inside teh cell phone case ?  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.

### ⭐⭐⭐⭐⭐ Good rfid fobs
*by A***Y on 10 October 2025*

I used these to stick on the back of my phone to access my apartment door sensor. Easy to program and stick on well.

### ⭐⭐⭐⭐⭐ Copied my building key fob and worked great!
*by T***S on 27 August 2024*

Took the tag to my local key maker and they made the copy of the key fob like you would normally do and worked great ! Stick the sticker between my iPhone and the case and ready to go (make sure you put it at the bottom not the top otherwise the reader picks up Apple wallet) With my flat smart lock and this, I don’t have to carry keys or fob around anymore just my phone.
