The CR80 Adhesive PVC ID card is a great for general use. The same size as a standard credit card, the CR80 Adhesive is the most commonly sized card and can fit in most ID card printers.
While it can fit onto your standard clamshell proximity card, the CR80 Adhesive card will lay on top of, not within, the proximity cards borders. For a slightly smaller-sized card, check out the CR79 Adhesive card.
Measured after the adhesive paper is peeled, the CR80 Adhesive PVC card comes in 10 mil thickness.
When deciding if this card is right for your operations, consider your printers specifications. It must handle cards that are 16 mil to 30 mil in thickness to accommodate the adhesive paper backing.
NOTE: Most card printer manufacturers recommend using mylar backed cards for best results.
