RFID door lock shield and NFC

[Mickdula]

Hey guys,

Wanna build a read/write struck lock for the front door and wanted to use an nfc setup. Anyone know if the dirt lock shield would accept any nfc reader/writers.

You can use any reader that has serial data between the reader and Arduino software serial. Reply with a link to the reader you're considering and we can have a look.

I have a rfid-rc532 from sainsmart that they claim is read only to rfid. Others say it's read write rfid and nfc. Also the rc522 has 8 pins in the board and the door lock shield has 4 pins in can you help me with hook up.

The RXD and TXD of your ebay reader would connect to the "RFID reader" area on the shield, along with 5V and GND.

The RC522 uses either the SPI or I2C buses, which are different altogether. SPI is digital pins 10~13 on the Arduino/Eleven and I2C is A4/A5. Make sure you can get the documentation with any reader you buy.

What about this one. Seems the same except it has sda and scl instead of tx rx. http://pages.ebay.com/link/?nav=item.vi ... 0850345635

SDA/SCL means I2C, so again use A4/A5.

Would a rfidread-rw from priority 1 be a better, simpler solution?

Unless you're restricted by price, the next consideration would be the physical range available with the reader (if that's an issue). If not, then yes go for the P1 reader used in the book as Jon has tested it.

hey guys, has anyone had any luck getting ultralite or mifare classic cards going with this shield?
There seems to be a wealth of 125k info but little HF/NFC integration.

Does Priority 1 do a HF reader?

It would appear not:

However you can still use other readers/NFC etc. and use this shield to control the door strike.
