What are the differences and uses of IC cards, ID cards and access cards?

The biggest difference between IC cards and ID cards is that IC cards can write data, but ID cards cannot\x0d\Currently, the most commonly used identification cards in access control systems are the following cards: EM cards, and the M1 cards we often talked about before.

, and TM card, and CPU card, etc.

Currently, EM cards and M1 cards occupy almost the entire access control card application market.

Therefore, when we choose the card to use, it is best to choose EM card or M1 card as our main card.

Because for other cards that are not commonly used, whether it is the maturity of the technology or the matching of accessories, it will bring us a lot of trouble.

And as the market share shrinks, these cards will inevitably gradually withdraw from our application market after a period of time. In this case, the repair, expansion, and transformation of the access control system will bring unexpected troubles.

\x0d\In fact, for ordinary access control applications, EM cards are undoubtedly the most practical type of access control cards. It is characterized by long card reading distance, high market share, and has relatively mature technical practices.

However, the biggest disadvantage of this type of card is that it is only a read-only card.

If we need some charging or transaction functions at the gate, then this kind of card is really not up to the task.

\x0d\For users who have consumption management needs, if they need some simple records or transfers, then the M1 card is enough.

Of course, if we still need some more detailed content identification or transaction activities in the application of access control systems, then the CPU card supported by the latest technology has stronger security than the traditional M1 card.

In the long run, CPU cards are increasingly eroding the M1 card market.

Therefore, if your device has the possibility of system expansion in the future, I think the CPU card will be more developed.

\x0d\As for which card is more cost-effective to use, it depends on your specific needs. If you only need a system with a certain function, of course the simpler the better, the capital investment will be smaller, but if there are many systems involved and require

To support upgrades and expansions in the future, it is best to use better cards, but of course the cost will be higher.

This depends on your needs and can be measured.
