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.
