Seeed NFC Shield V2.0
Using NFC technology to read/write tags, to communicate with Android 4.0+ and to emalute NFC type 4 tags
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).
