At the 27th annual German Chaos Communication Congress hacker conference ("27C3") in 2010, German free software programmer Harald Welte showed that it is possible to artificially change the amount of money stored on a first-generation EasyCard—based on the MIFARE Classic—using nothing more than a USB RFID reader and a laptop computer running open source software.
In August 2003 Harald Welte was made chairman of the coreteam, and in April 2004, following a crack-down by the project on those distributing the project's software embedded in routers without complying with the GPL, Welte was granted a historic injunction by a German court against Sitecom Germany, who refused to follow the GPL's terms (see GPL-related disputes).
