RFID sniffer

About this project

RFID is everywhere. Use the easy to build RFID sniffer to find out if objects are tagged.
The RFID sniffer is a simple analog electronic circuit which can detect the presence of 13.56 MHz RFID tags. These tags are commonly used in all kinds of plastic cards like access badges, bank cards, library cards, loyalty cards and so on. Also many other objects may carry RFID tags without you knowing it. Books, toys, and even clothing might be tagged. Carrying tagged objects with you can reveal your identity or whereabouts to anyone equipped with the appropiate tools to read RFID tags.
The RFID sniffer helps you identify which objects are tagged, and which are not.

Arduino libraries now on Github

Thankyou for your great work.

I just read https://github.com/marcboon/RFIDuino/blob/master/SL018/SL018.cpp ,
On line 30 it say --> address = 0x50

Look like you hardcode the reader's I2C address.
Is there any way to sign another address from Arduino Sketch ?
