The OmniClass cards are laminated PVC cards that can be printed on both sides using a dye-sublimation or thermal transfer card printer. They can also be slot-punched on the short side for vertical orientation (portrait). In addition to OmniClass cards, key fobs and stickers are also available. The rugged, molded key fobs include a slot for use with most key rings or badge clips. The stickers are thin, flat polycarbonate discs that have an industrial adhesive backing. The stickers are non-removable and can be affixed to the back of existing 125kHz proximity, Wiegand or magnetic stripe access cards, non-metallic surfaces of PDA's, cellular phones, briefcases and other personal items.
