NFC RC522 or PN532 with Pi?

Hi Folks,

Has anyone used one of the NFC readers (RC522 or PN532) with Processing for Pi? They both have SPI interfaces, which should work with the Pi, but without a library I’m in over my head looking at the low level docs for SPI communications. There are libraries for this readers in both Arduino and Python - how feasible would it be to port one for Processing for Pi?
