      Hi,

      I wanted to know if the following reader would work for the NFC ring. I am making my own door lock with the raspberry pi and would really like the NFC ring to be able to communicate with my raspberry pi which in turn opens my door.

      Parralax USB Reader: http://www.active-robots.com/rfid-reader-usb-and-tag-sampler-kit.html
      Documentation: http://www.active-robots.com/fileuploader/download/download/?d=0&file=custom%2Fupload%2FFile-1312668601.pdf

      NFC Ring: 13.56 Mhz
      Parralax Reader: 125Khz

      I am pretty confused about this as on the FAQ page for the NFC ring it says it is compatible with the Pi. From the details given above, I would say it probably would not work but I really need some confirmation on that. If I am using the wrong reader then can someone link me to the correct one that I can buy in the UK.

      Thanks.

        Mmm, regardless of anything else if that reader is at 125kHz then it will not work no matter how angry it makes you trying.
        The ring is at 13.560MHz, you need a reader at 13.560MHz which will be capable of handling NFC.
        It's compatible with the raspberry pi in that if you hook up an appropriate reader you will be able to use it with that, otherwise you're not going to have much luck at all.

          That is perfect, that is all I needed to know :)

          Looks like it's time to replace the reader.

            I've never used a pi, so I'm not up to speed with them but if they can handle the same kinds of connections that arduino does then you might be able to use an elechouse pn532 reader with that. It rates as my favourite reader for arduino and compatible.

                Looks pretty good! It is also significantly cheaper than the one I brought haha!

                I'm guessing from a quick look that it returns data back just like a serial connection. If so then it should be pretty easy. In any case, I will keep this thread up to date in case anyone else is in the same situation in the future :)

                      Yeah I just brought one from eBay and have successfully made it work with the Pi. Just waiting on my ring now - wonder when it will arrive.

                            Hi....I am trying to connect a Rapsberry pi to parallax Propeller microcontroller. My intend is to use the propeller read comands from the pi and control motors and read sensors and relay the information back to the Pi on a mobile robot. I intend to add vision eventually using OpenCV or some other vision library so the Usb port cannot be used for communications. Any information regarding how to do the communications would be appreciated. Oh and one more thing my programming experiences are primarly C++ and Java with a little basic.
