Elektor June 2009 ATM18 RFID Savvy EM4095, ATmega and Bascom

• RFID appears to be well on its way to becoming a technology of the future. Many people mistrust this technology, while some see it as the answer to every problem. One thing is certain: these tiny devices will be everywhere around us in the future, whether or not we notice them. Our ATM18 board provides the ideal basis for experimenting with RFID devices and implementing your own ideas.

• EM4095 Reader
• Compatible with RFID tags EM4102 and EM4200

Elektor June 2010 Wireless Electricity meets RFID

• Wireless Electricity meets RFID Do-it-yourself wireless RFID sensor systems Published in issue 403, June 2010

In this article we describe a do-it-yourself RFID reader- as well as a way of making your own RFID tags" 
What's more, we show how to make RFID tags that include a transducer, opening up the possibility 
of making RFID sensors. The tiny sensor module operates without an internal power source and delivers 
its readings to the RFID reader for further processing.

• Reader: ATtiny2313, replacing EM4095
• Tranponder: ATtiny13, replacing EM4102
• Software was written for the reader in C (WinAVR/GCC, Only Source, No Project-file).
• In Assembly for Transponder
