The difference between membership magnetic stripe cards and smart IC cards

    We see that some shopping malls and supermarkets use cards with black magnetic stripes on the back, while others use IC cards that are sensory. Those with magnetic stripes only need to swipe the machine to complete the entire shopping process, while those with contactless IC cards only need to be placed on the device for a short while to complete the transaction. But what are the differences between them?

1. IC cards have a long service life. Relatively safe. The price is higher than magnetic cards. 　　
2. When using magnetic stripe cards, be sure to use a computer, using a dedicated card reader to read the card number and extract information from the database. IC cards can be traded through a small card reader, eliminating the need to set up a computer at every point of consumption.
3. Good security and confidentiality. Information on the IC card can be read, modified, or erased at will, but a password is required.
4. IC cards have data processing capabilities. When exchanging data with the card reader, the data can be encrypted and decrypted to ensure the accuracy and reliability of the exchanged data; Magnetic cards, however, do not have this feature.
5. Large storage capacity. The storage capacity of the magnetic card is about 200 digital characters; The storage capacity of IC cards varies by model, ranging from a few hundred characters to over a million characters.

    I want to add one more thing: magnetic stripe cards are prone to demagnetization, and once demagnetization occurs, if you don't write the magnetization, the card is essentially wasted. IC cards, on the other hand, do not have this problem because the IC card's chip is inside.
