## Questions & Answers

**Q: Anyone successfully manage to write to these with a proxmark 3 (rdv2)?**
A: Yep! No issues at all.

**Q: whats the maximum amout of bits the card can hold?**
A: hi.
These cards are IR antennas for access reading pads locks.
I don't think or know to be any bits (memory) on them.  
Depending on the reader they can go to higher levels of frequency.
I tried them for a hotel I worked for--no luck..
Unfortunately you have to keep on reading.

Best thing woul be a hotel system worker.

Good luck
Best, Doru

**Q: do they come programed**
A: Hi AlexNo,they are without programed,because different client need to write in different format.and the chip is original chip.if you want pre-programed,it's more cheap,and it's read only,can't writable.see the link below:https://www.amazon.com/dp/B01M1L7NHIThanks.RegardsDavid Hong.

**Q: Can I punch a small hole in this and it still work?**
A: yes,but please be careful of the coil inside.
you can take a light to check where is the coil,and be careful to punch the coil.

Thanks.

### ⭐⭐⭐⭐⭐ Worked Excellent
*by G***N on 14 July 2024*

The T5577 card worked perfectly with my Flipper Zero. It came completely blank, with no pre-existing data, unlike some other cards that aren’t writable. I had no trouble at all writing PAC/Stanley data onto it. Highly recommended for anyone needing a reliable and writable card.
