How do I include magnetic stripes on my cards? Debit and credit cards use HiCo magnetic stripes, employee ID programs, and student and staff ID cards at many schools and universities. When would you use HiCo cards? Anytime you need a card that will be swiped frequently and needs to last a long time.
They require much more energy to encode or to erase the data, making them less susceptible to interference from magnets or to daily wear and tear. HiCo cards, or High Coercivity, are between 3 Oe and designed for long-term use. When would you use LoCo cards? Anytime you don’t need a card to last a long time, making them ideal for parking garage tickets, public transit systems, visitor IDs, and hotel room keys. LoCo cards made from PVC or composite materials are often reused. As a result, the encode will last a shorter amount of time and is more susceptible to interference, especially from strong magnets. These cards fall between 0 and 300 Oe, making them easier to encode and erase the data on the card. LoCo, or Low Coercivity, cards are designed for short-term card use. Not sure which cards you’re already using? The easiest way to tell is their color – LoCo cards have a dark brown magnetic stripe, while HiCo cards are black. Magnetic stripe strength is measured in Oersteads (Oe), or how much energy it takes to change the polarity of the card to encode, or erase, the card. They both hold the same amount of data, but have different durability for short-term or long-term use. With mag stripes, you have two types of encoding to choose from, depending on how your cards will be used. Magnetic stripe cards are used in a variety of card programs including employee IDs, student and staff IDs, retail rewards cards, membership programs, and more.
