What material are magnetic stripe cards made of?
    In daily life, magnetic stripe cards are often used, and they can be used for services, such as spending and earning points. So, what material are magnetic stripe cards made of? Magnetic stripe cards are a type of magnetic recording media card. It is made of high-strength, heat-resistant plastic or paper-coated plastic, which is moisture-proof, wear-resistant, and has a certain degree of flexibility, making it easy to carry and relatively stable and reliable to use. Usually, one side of the magnetic card is printed with explanatory and prompt information, such as the card insertion direction; The other side has magnetic layers or magnetic stripes, with 2-3 tracks to record relevant information. Magnetic stripe cards can be divided into PET cards, PVC cards, and paper cards depending on the magnetic layer structure. Depending on the magnetic layer structure, magnetic stripe cards and fully coated magnetic cards can be further divided.

    There are three magnetic tracks on the magnetic strip. Track 1 and Track 2 are read-only tracks; information recorded on the track can only be read and cannot be written or modified during use. Track 3 is a read/write track; it can be read or written during use.

    Track 1 can record numbers (0-9), letters (A-Z), and some other symbols (such as parentheses, separators, etc.), with a maximum of 79 numbers or letters.

    Tracks 2 and 3 can only record numbers (0-9). Track 2 can record up to 40 characters, and track 3 can record up to 107 characters.

    Currently, this material is widely used in magnetic stripe cards, and magnetic stripes are divided into high-resistance and low-resistance types. Even with the same material, the quality and effect can differ. If you need it, feel free to contact me.
