Introduction composite card：
Composite card, the most complete function of intelligent induction card
Composite card is also a common smart card in our life. It consists of a variety of chips. Composite card consists of high frequency card, high frequency card or high frequency card and low frequency card. It is the smart sensor card with the highest technical content and the most complete function in China.
Composite card Composite card
Composite card of ID + IC card Sensing low frequency card + contact card
Composite card is also known as multi-function card, that is, different cards are compounded into one card to achieve the multi-purpose of one card. 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 a high domestic technology, the card can adapt to several different tools and inventions more complete function of intelligent induction card, but also can add magnetic stripes, bar codes, visual card function to do more multi-functional composite card.
Common types of composite cards.
1. Composite smart cards and magnetic stripe cards
Contact IC card and magnetic stripe card composite: for example, SLE5542 and high resistance magnetic stripe composite
RF card and magnetic stripe card composite: for example, MF1 S50 and low resistance magnetic stripe composite
2. RF card and contact IC card composite
Contact low-frequency card IC composite card: for example, ID and SLE5542 composite
Contact high frequency card IC composite card: for example, MF1 S50 and SLE5542 composite
UHF card and contact IC composite card: for example, the composite of GEN2 and SLE5542
Third, the composite of low-frequency card, high-frequency card and UHF card: also known as dual-frequency card.
The compound of low-frequency card and high-frequency card: such as the compound of ID and MF1 S50
The combination of low-frequency card and UHF card: for example, the composite of ID and GEN2
Compound HF card and UHF card: for example, MF1 S50 and GEN2
Fourth, the combination of low-frequency card, high-frequency card and UHF card: also known as three-frequency card.
The combination of low-frequency card, high-frequency card and UHF card: ID, MF1 S50 and GEN2 composite
5. two protocols of high-frequency card composite a machine try not to read the same composite card in two chips at the same time to avoid interference.
Composite card is a card with multiple IC card features. The card uses contactless design, direct deduction through the radio frequency mode, safe, convenient, wear-resistant and fast. At present, it is mainly used in banks, schools, government and other institutions.
