About iCLASS Technology
Creighton University began issuing iCLASS® cards in January of 2006. A proprietary technology made by HID, iCLASS® cards combine magnetic stripe functionality with a contactless smart card. Based on RFID, these smart cards use a high frequency radio technology, versus the low frequencies used in proximity cards, to communicate with door readers.
Because the iCLASS® cards do not contain a power source (passive RFID), they must be presented within two to four inches of the reader. Each card has an antenna and chip embedded in it to facilitate door access. If the chip is broken or the antenna severed, the card will no longer function.
