Honeywell's OmniClass credentials are designed to work with the OmniClass readers. The OmniClass product line, built on 13.56MHz technology, is RFID based and provides excellent contactless sensing range (up to 4.5").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.
