ValuProx 125khz LGGMN ISO composite PVC-PET Proximity cards wtih mag stripe are equivalent to other 1536 configured LGGMN proximity cards that are equipped with magnetic stripe technology, and ideal for applications such as photo ID and access control. The ValuProx 125kHz LGGMN PVC-PET Prox cards with mag stripe are the size of CR80 30 mil card (approximate size of a standard credit card), made of a resilient composite of 60% PVC and 40% PET, and feature a graphic-quality glossy surface on both sides, making them suitable for printing with any dye-sublimation card printer for professional-looking credentials. Composite cards are recommended for use in laminating and retransfer printers because they are more resistant to heat than standard PVC cards, as standard PVC cards may warp from the intense heat used in both of these processes.
