Introduction of composite card and common types of composite card
Composite card is equivalent to compounding two or more different types of cards with different chips into one, so that a card has the functions of multiple cards at the same time. This card is collectively known as the composite card, very common IDIC composite card, IDM1 composite card, M1 contact IC composite card, high-frequency low-frequency composite card, high-frequency ultra-high-frequency composite card, low-frequency ultra-high-frequency composite card, etc.

Second, the composite card will interfere with each other when used?
Composite card is either a composite card of different frequency bands or a composite card of different protocols. Therefore, in the process of using the composite card, different frequency bands or protocols of the card reader will only read the corresponding part of the composite card. Therefore, although the composite cards have different types of chips between them, they will not interfere with each other. Of course, if you want to make a good composite card, the card manufacturer also needs to have certain skills in order to reasonably arrange different coils and chips on one card without affecting the mutual function and effect. Such as
1, induction low-frequency + such as: ID + IC card composite card (IC, ID composite card, IC, ID composite card), T5577 card + M composite card 1 card, etc..
2, induction low frequency + contact IC such as: ID card + composite card 4442 card, T5577 + composite card 4442 card, etc..
3, induction high frequency + such as: M1 card + composite card 4442 card, Legic card + composite card 4428 card, etc., IC card + 4442 card composite card.
Third, what circumstances will use the composite card?
For example, many companies in the access control system, restaurant food sales system, time and attendance system, elevator control system, parking system using system equipment is not uniform, now need a card, the systems are not compatible, the entire system equipment removal is too wasteful, the use of composite cards is a more appropriate choice. For example, we commonly access control composite card, elevator composite card, IC composite card, ID composite card, etc.

Fourth, what are the common styles of composite cards?
Our common composite cards are usually made into cards or keychain card style, card style can print color pictures, color pictures can be designed according to the needs of customers. Keychain composite cards can only print 3-5 single-color words or laser engraving. Because there are at least two kinds of chips and coils in the composite card, the composite key card is larger than the ordinary 2 or 3 keys, such as 1 key and 6 keys.
