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? :)

Hi....RFID (Radio-Frequency Identification) is commonly used nowadays in security systems such as door locks. RFID sets/modules can be very affordable, such as the Mifare MFRC522 chip we will be using in this tutorial.The MFRC522 RFID readers comes with a RFID’s tag card. The MFRC522 communicates with cards or tags up to 1cm using a 13.56MHz electromagnetic field, then sends the data to an Arduino board through SPI communication.
