Tips
Antenna location affects user experience and software designThe communication speed has effect on user experience. Maximumdata rate is 424 kbits/sDo people know how to use NFC? Do they know it works by touch?
If they do, how they know when to touch tag/phone?Teach the user at least in the first time?
Application can start by touching a tag. Try to use that if it suits yourapplication
Proved that users like thatWe have been using mostly Mifare 1k tags in our experimentsThe Catch: Easy User Interface!
