What are the processes for magnetic stripe cards?
    Everyone knows magnetic stripe cards are ordinary PVC cards with a black magnetic stripe on the back. This is the well-known magnetic stripe card. The main processing of magnetic stripe cards is this magnetic stripe; without this magnetic stripe, it wouldn't be called a magnetic stripe card. Next, I will mainly talk about the main manufacturing processes of magnetic stripe cards.

1.Magnetic stripe card productionThe embossed code process
    Why use this convex code process? Because once information is written into the magnetic strip, the information is invisible. For example, if the number on the magnetic stripe is 888, customers don't know the card number. If the number increases, each card needs to be scanned to find the number, which is very troublesome. The embossed code displays the number information directly on the card's surface, making it easy to understand.

2. Magnetic stripe manufacturing process for magnetic stripe cards
    As mentioned at the beginning, if there are no magnetic stripes, then the card isn't called a magnetic stripe card. Magnetic stripes usually have three tracks: the first can hold numbers and letters, the second can only write numbers, and the third can only write letters. Usually, we write on the second track, because numbers can be made infinitely, which English can't do.

3. Signature strip craftsmanship for magnetic stripe cards
    The main function of this signature slip is to sign the holder of the magnetic stripe card, letting others know that the card already has an owner. The main purpose of this process is to look good; whether or not you sign is not that important.

    Alright, the main processes for magnetic stripe cards are roughly these three. Of course, I'm talking about the main processes here. The most important is still adding magnetic stripes, because magnetic stripe cards without magnetic stripe processing are not good magnetic stripe cards.
