At present, the commonly used driving training IC cards have the following 2 types:
One is the non-contact IC card, commonly used cards are S50, S70 and so on. This card is the same type of access control card and bus card that we commonly use. There is no contact between the card and the reader. The information is read and written by electromagnetic induction. S50 has 1K bytes of storage space and S70 has 4K bytes. storage. It can meet the needs of recording student training information.
The second is contact IC card, commonly used include 24C series, SLE4442/4428 and so on. The reading and writing of this card must be in contact with the reading and writing interface of the card reader. The reliability is not as good as that of the non-contact type, but some traditional devices have always used this method. The 24C series includes a variety of specifications such as 1K/2K/4K/8K/16K/32K, which can meet the requirements of trainee training information recording. The only deficiency is that this is always a memory card, which does not have encryption function, that is to say, anyone The data inside can be rewritten, which requires the driving training system to consider how to solve the tampering of the information as a whole; SLE4442/4428 is a card contact IC card with logical encryption, which can control the rewriting of the content through a password, and has certain safety.
