Thanks Gordon. I've tried the 5v and 3.3v supply & GND is connected ok I believe. I've tried the other SPI ports, so I suspect it maybe the card. What should I connect SDA pin (on the RFID board) to? Your original page says B2 but I think that's not an accessible pin.
The image shows how I originally wired it up.
I've ordered another card (red board) so I'll see how that fares when it arrives.
