White PVC Cards with HiCo 3 Track cards feature a standard credit-card size in 30 mil thickness and come in an array of colors including fluorescent and metallic - great for card programs that want to be easily recognized. White PVC with Mag Stripe are made from the same durably PVC material. Perfect for membership and loyalty programs, gift card programs, identification, and much more. High coercivity mag stripe cards are ideal for applications where the cards will be frequently swiped or need to have a long life, such as access control and/or time and attendance cards. HiCo mag stripe cards store information more securely than low coercivity magnetic stripe cards because of the higher level of magnetic energy required to encode them. This also makes information on high coercivity mag stripe cards harder to erase and more resistant to damage from most magnets or magnetic fields. High coercivity (HiCo) cards can generally be identified by a black magnetic stripe, whereas the mag stripe on low coercivity (LoCo) cards is generally more brown in hue. HiCo 3 Track cards can be encoded on track 1, track 2 and track 3. Cards provided DO NOT come encoded. Buyer must encode data with buyers specification with mag encoder. For printing use - you can use direct-to-card printers or reverse transfer printers, these cards will not print on inkjet printers.
