So I got one of those fancy NFC cards from moo. It makes my phone go *beep* ...It'd be fun to reprogram it to do something a bit cooler.

I modified @harper's with t.co/KTvuP87Q … worked OK but there are more things NFC can do than what that app supports.

that app "can't format this kind of tag"

the problem seems to be that Moo "NFC" cards have Mifare classic chips, which are not compliant with NFC standards or my Nexus 4.
