Sonmicro RFID Processing library

Last year we made a Processing library for the Sonmicro SM130 RFID read/write module together with Jørn Knutsen and Tom Igoe. The SM130 is a little module that lets you read and write to Mifare RFID tags. The Sonmicro Processing library is a good and flexible tool for exploring RFID interactions. One of the things we have been doing with it is playing with the London Oyster card and writing messages to the memory on our office access-cards.

Tom recently used an updated version of this library in his RFID workshop at ETech 2009 and has written a series of thorough tutorials on his weblog. The tutorials covers the basics of the library and also shows how a SM130 can be used with an Arduino: Sonmicro RFID reader for Processing, Reading Mifare RFID tags, Writing to Mifare RFID tags, Arduino-based RFID reader and RFID to Web interface.

In a future post we will look more closely on the technicalities of designing behaviours with RFID readers, presenting our tools for both the Sonmicro SM130 and the Innovation ID12.
