For smart cards, you can’t beat the easy of magnetic stripe encoding. Most ID card printers have an optional magnetic stripe encoding module, and card design software makes it easy to add your data. But when adding magnetic stripe cards to your ID card program, do you know the difference between HiCo and LoCo cards?
LoCo cards, or low coercivity, have a magnetic stripe that is encoded with a lower strength magnetic field. This makes the cards ideal for short-term use, like hotel room keys which will be erased and re-encoded after every use.
HiCo cards, or high coercivity cards, have a stronger magnetic stripe. This allows the cards to hold data for longer periods of time, and also makes the data more secure. HiCo cards are best used for payment cards like college meal plans or ATM cards.
