Given the recent announcements from MS about NFC support in Windows Phone 8 / Windows 8 (and the fact that Android already has this in certain phones), I am thinking a NFC Module that can talk to these devices may be a good idea. What do you think? With this in mind does anybody know about the NFC that these devices use? and have any suggestions as to NCF chips antenna etc that will be best to include in the module?

An NFC module would be really cool. There are a ton of cool interactive projects that could be done with Netduino and mobile phones (like those running Windows Phone 8). Chris

NFC would be really cool, however it is quite expensive to get going with, and there are several competing technologies (much like RFID, where you cant really get a universal reader that reads everything e.g. Mifare wont work with legic, which wont work with Hid. That said i would love to see NFC become easier to integrate with, and a GO! module would certainly have a lot of applications, although if it were to be used for payment SSL support would be necessary....

Must admit payment is the last thing on my mind so just simple communication and tap to share stuff would be my target.

Well I am one step closer to this as you can see here: Work In Progress. Not as impressive as the QuadroCopter but a start down the road of module development.

Not sure if the reader will be compatible with most phones etc but it does read the same sort of tags that phones are supposed to be able to read :-s

What sort of RFID reader are you using? There are two basic types - 125kHz and 13.56GHz. NFC is pretty much two-way comms over a 13.56GHz RFID link. If you get a 13.56GHz module you should be do basic stuff like query the "card serial number" where the phone acts like a simple tag. There's more from there, but that's a good start. I bought this module fairly cheaply on eBay and could do some simple comms with my Galaxy Nexus. http://www.ebay.co.u...:EOIBSA:GB:1123 If you've gone for 125kHz, don't worry. Anything work you do should transfer across fairly easily.

Aha yeah using a 125Khz module at the mo so looks like some purchases to be made. Also look like a more expensive option

[Mike Hole]

Going to get one of these: http://www.coolcompo...6mhz-p-504.html Does look up to the job to you?

[Fred]

That should do it. I can recommend UK eBay seller nfc-supplies for things like Mifare sticker tags. If your current phone doesn't have NFC you could stick one of those on the back (or under the battery cover) and at least detect its presence. If your Android phone does have NFC then there are some useful free apps by NXP (NFC TagWriter and NFC TagInfo) that lets you read from and write to the 13.56GHz tags from your phone.

Great stuff cheers Fred
