Another way to put NFC tags on your hand is to laminate one into your nail polish! We pulled this small tag out of one of the leather fobs in the store, and trimmed the plastic close to the antenna until the layers peeled apart, then removed any stick residue with rubbing alcohol.
Curve the antenna coil over a round object like a ring mandrel. The tag should fit snugly to the curve of your nail without springing up away from it.
Stick the tag to the base coat, using a piece of clear packing tape to keep it in position if necessary. Cure the base coat layer in your UV lamp for ~2 minutes, then remove the tape. The tag should be pretty stuck to your nail by now!
