I am starting developing an application using NFC.

I bought already a Nokia 6212. I would like to know what else I need to buy.

I need to buy some tags:
- Which are the tags compatible with this phone.
- Any suggestion where to buy them?

Can I write the info on the tag using the phone?
- Is there any sample code for that?
Do I need a tag writer instead?
- which one you'd suggest?

Thank you very much for the help!
