Composite card is also known as multi-functional card, that is, different cards compounded into a card, in order to achieve a card multi-purpose. Generally there are high-frequency card plus contact card composite card, high-frequency card plus low-frequency card or low-frequency card and contact card composite card, is the domestic technology, the card can adapt to several different tools and the invention of a more complete function of intelligent induction card, you can also add the magnetic stripe, bar code, visual card function to do more multifunctional composite card.
Introduction of composite cards, composite cards can be divided into several types
For example: MF1 card (or ID card) and SLE442 card combination, that is, the combination of radio frequency card and contact card; ID card and MF1 card combination, that is, the combination of low frequency card and high frequency card; MF1 card (ID and magnetic stripe card (low resistance magnetic stripe or high resistance magnetic stripe) combination, that is, the combination of radio frequency card and magnetic stripe card.
Common types of composite cards are.
Induction low frequency card + high frequency card
such as: ID + IC card composite card (icid composite card, idic composite card), T5577 card + M composite card 1 card, etc..
Induction low-frequency card + contact card
such as: ID card + composite card 4442 card, T5577 + composite card 4442 card, etc.
3、 Induction high frequency card + contact card
such as: M1 card + composite card 4442 card, Legic card + composite card 4428 card, etc., IC card + 4442 card composite card.
Composite card is a card multi-purpose IC card characteristics. The card adopts contactless design, through the radio frequency mode direct debit, with security, convenient, wear-resistant, fast characteristics.
Composition of composite card
The simple combination of smart card and magnetic stripe card or the simple combination of RF card and contact card, or the simple combination of low-frequency card, high-frequency card, ultra-high-frequency card, and the simple combination of high-frequency card. It is mainly used in banks, schools, government and other institutions.
