ISO14443
ISO/IEC 14443 is a 4-part RFID standard for short-range “Contactless Proximity
Cards”. Adopted in 1999 and 2000, ISO14443 has become the worldwide standard
for cashless payment and contactless stored value applications.
 ISO14443-1 defines the physical characteristics of an RFID card.
 ISO14443-2 specifies two types (A and B) of 13.56MHz air interface and
modulation methods used for communication between tags and readers.
 ISO14443-3 specifies the anti-collision method for selecting one tag among
many.
 ISO14443-4 defines the high-level protocol and method for data exchange
between tags and readers.
