Classification of contactless IC cards
Dec 05, 2018

1). Radio Frequency Encryption (RF ID) is often referred to as an ID card. Information access to the RF card is done by radio waves. There is no mechanical contact between the host and the RF. Such as HID, INDARA, TI, EM, etc.


Most schools use rice cards (larger thickness), access cards, and ID cards.


2). RF memory cards (RF ICs) are often referred to as contactless IC cards. The RF memory card also accesses information via radio. It adds RF transceiver circuits to the memory card. For example, MIFARE ONE.


Some city buses used in the early days of the city, some used in the school, hot water cards, are RF memory cards.


3). RF CPU card (RF CPU) is usually called active card, which is based on the CPU card. The CPU card has its own operating system COS, which is called a real smart card.


The bus card of a big city, a financial IC card, and a meal card of a very small number of schools belong to the RF CPU card.
