plastic cards usually serve as identity documents, thus providing authentication. in combination with other assets that complement the data stored on the cards, like pin numbers, they also serve authorization purposes, most often as bank cards for allowing their holders to do financial transaction.
there are several types of PVC cards, including:
standard PVC: a versatile option that works well with direct-to-card printers.
composite: a combination of PVC and PET (polythene terephthalate) that's more durable and can be used with laminating printers. composite cards are often used in industrial settings or outdoors.
rewritable: has a rewritable surface on the side and a PVC finish on the other. these cards can be erased and reprinted up yo 200 times.
earth- friendly bioPVC: made from 99% PVC that biodegrades within nine months to five years.
clamshell: larger and thicker than standard cards, clamshell cards can be reused by removing the adhesive. they are often used for door access by businesss that provide credentials for contractors or temps.
