Need tutorial for a USB RFID kit.
On eBay I got a RFID kit that uses a 125KHz exciter and reads or writes a card or one of 5 key chin tags. Passive mode.
Here is a photo.
It appeaser to work. It can write to a key chain tag.
This device could be use to do my Windows password. But not yet, I do not understand how it works and the software has not source code.
Here is a screenshot from the reader.
What is lacking is documentation. I am very ignorant about this kind of thinmg and I got it to learn more about how it works.
The chip is a type ATA5577 and there is a data sheet, but that does not tell me much.
Does anybody here have experiences with these passive RFID tags?
Where can I find a tutorial?
