Javier Montaner has released a new Arduino library for the Seeedstudio NFC shield. The new PN532 library uses SPI HW implementation from official Arduino SPI.h library in contrast to the original PN532 library from seeed which uses a dedicated SPI SW implementation in the PN532.h library.
You can download the Javier’s NFC library and supporting docs from GitHub.
