Based on this recent work from Londonite Dhani Sutanto, Becky over at Adafruit just posted this cool tutorial on how to install the antenna and chip from an RFID passcard, such as the MBTA’s CharlieCard transit pass, inside your iPhone. The process is quite simple: just dissolve away the card plastic in acetone, extract the antenna and chip, and install under the iPhone backplate. Depending on what kind of backplate you use, you may also have to insulate with paper and/or tape.
