The first loop, used for initial authentication, entails scanning for two or more types of NFC tags. And the second loop, invoked after initial authentication, scans for a smaller subset of the two or more types to conserve battery power.

Abstract: A magnetic head is held by a side wall through a head fixing fitting so as to freely advance into and retreat from a card sliding groove. First and second head urging levers are swingably supported through a pin. In a standby state, the magnetic head is away from the card travel groove, and card engaging sections of the first and second head urging levers are staying in the card travel groove.

This causes the first head urging lever to push out the magnetic head into the card travel groove so that the magnetic head makes contact with the magnetic card.
