[Music] [Applause] [Music] hey everyone today i want to talk about the t5577 chip now we use this chip in some of our products like the xcm and next implants and the reason this chip is interesting is that in the low frequency family of transponders so this is the 125 kilohertz family of of rfid tags and transponders typically you'll see a lot of these kind of cards used so this is like a card here with some numbers printed this is the id number of the card printed in decimal format you'll see hid type cards or badges there's a little lanyard connection there or key fob something like this now when these kind of cards or fobs are operating on 125 kilohertz that's interesting because usually it means these cards are not secured in any way any reader can read the id number or just look at the number but any any reader can read any of these things so there's no like hacking or anything tha
