A proprietary technology from HID based on the RFID standard for "proximity" cards. iCLASS uses a high frequency computer chip to communicate with compatible readers. Currently, the technology is only used for door access on campus.  The Mike and Josie Harper Center, Opus Hall, and the Parking Garages are some of the buildings on campus which use iCLASS technology.


A stored value account in which the user pre-deposits funds to use for the bookstore, print centers, dining services, libraries, mail center, vending machines, and printing services. JayBuck$ carry over each semester.

Prox Card

Proximity Cards refer to an older technology, also based on RFID, which use a lower radio frequency to communicate with door/gate readers.  True proximity cards have a greater range, but the computer chip contains a power source.  Creighton-issued ID cards are not "prox" cards.


Radio Frequency Identification (RFID) is a technology which uses radio waves to enable devices to communicate. Developed prior to World War II, the technology became popular in the 1980's and 1990's. It currently has many applications, including automotive, electronic door access, inventory and asset tracking, libraries and livestock.

ID cards issued by Creighton incorporate high frequency RFID technology, also referred to as contactless or "smart cards".
