Datasheet

NFC Shield from Seeed Studio is based on NXP PN532.
Note that this shield doesn't use the standard SPI pins, but relies on non-standard 6-pin SPI header located at the shield bottom. To make it work you will have to bridge those pins as shown on the image (the green SPI pins).
Signal | Pin 1 | Pin 2 |
MOSI | D11 | SPI4 |
MISO | D12 | SPI1 |
SCK | D13 | SPI3 |
