Hey folks,

     I am new to this forum and a newbie to NFC/RFID. I was recently experimenting with NFC Tag Writer, and to my surprise, had some interesting results. By choosing the "link" dataset, followed by "URI" and inputting bitcoin:(any bitcoin wallet address, without the brackets) I was able to program an nfc tag to open up any bitcoin wallet (so long as the app name starts with "bitcoin") and further automatically goes to "send" to (input address). This is all fine and dandy and is useful for a receive NFC device. However, I am wondering if anyone knows of how to program an NFC tag properly to where it would do something to a "paper wallet sweep" upon contact with an NFC enabled mobile phone/device? All advice is greatly appreciated. Thank you.

Best regards,
CountCristo

I am very interesting in promoting further NFC development conversation as well, although don't have much to contribute at the moment...

IMHO it makes no sense for the NFC tag to do the work, but rather let the wallet software on the smartphone do the work. As in:
- read NFC data (encrypted privated key)
- ask user for password
- decrypt
- ask if to import into wallet (warn about potentional dangers) or wipe to wallet via TX
- etc. pp.

Edit: which would very similar to the existing QR Code scanning methods and would most likely require very little code changes for e.g. Mycelium.

Im not really here, its just your imagination.
