White PVC with Silver Color HiCo 2 Track cards feature a standard credit-card size in 30 mil thickness. White PVC with Silver Mag Stripe are made from the same durably PVC material as standard blank cards, but made with superior white stock PVC Cards. Perfect for membership and loyalty programs, gift card programs, identification, and much more. Silver 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. Silver 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. These cards are designed for use in direct-to-card printers with encoding capabilities. High coercivity (HiCo) cards can generally be identified by a black magnetic stripe, where as the mag stripe on low coercivity (LoCo) cards is generally brown. HiCo 2 Track cards can be encoded on track 1 and track 2. Cards provided DO NOT come encoded. Buyer must encoded data with buyers specification with mag encoder.
