NFC operates on frequency for data across is 13.56
megahertz and data which can be sent at 106, 212 or 424
kilobits per second. NFC technology is based on an initiator
and target where initiator starts communication by producing
magnetic induction field while target plays the role of receiver
by using this magnetic field to activate itself and performs
communication. Initiator and target can be stickers, key fobs,
tags, or cards that do not require batteries [3]. NFC tags are
integrated circuits which stores data that can be read by using
any NFC enabled device. NFC Forum has described tags into
four types Type 1-4, which differs from each other in storage
capacity and their uses [16].
