Product Introduction
It is made of high-strength, high-temperature resistant plastic or paper coated plastic, which is moisture-proof, wear-resistant, flexible, convenient to carry, stable and reliable to use. Usually, one side of the magnetic card is printed with explanatory and suggestive information, such as the direction of card insertion; On the other side, there is a magnetic layer or magnetic stripe with 2-3 tracks to record relevant information and data. Scope of application: there are three tracks on the magnetic stripe. The first two tracks are read-only tracks, and the third track is read-write tracks, such as recording book balances. The information of magnetic card is relatively simple and easy to read and write, easy to use and low cost, so it has been developed earlier and has entered many application fields, such as telephone prepaid card, toll card, reservation card, ticket, savings card, credit card, etc.
The characteristics of magnetic stripe card are: data can be read and written, that is, it has the ability to change data on site; The storage of data can generally meet the needs; Easy to use and low cost. These advantages make magnetic cards widely used, such as credit cards, bank ATM cards, membership cards, cash cards (such as telephone magnetic cards), air tickets, bus tickets, automatic sales cards, etc. The limiting factor of magnetic card technology is that the length of data storage is limited by the durability of the polarity of magnetic particles. In addition, the security of magnetic stripe card data storage is generally low. If the magnetic card accidentally contacts magnetic substances, it may cause data loss or confusion. To improve the security of magnetic card data storage, we must adopt other related technologies and increase costs. With the development of new technology, magnetic stripe cards with poor security performance are gradually replaced. However, under the existing conditions, there are still a large number of magnetic card equipment in the society. Coupled with the maturity and low cost of magnetic card technology, magnetic card technology will still be applied in many fields in the short term.
