Abstract: An authentication device and associated system and method for authentication. The authentication device may be used to verify that a possessor thereof is authorized to receive a prearranged entitlement. The possessor may be entitled to a good or service, access to a location, a discount, etc. Verification and arrangement may occur through communication with a central server, initiated by the authentication device, from any of a plurality of remote interfaces. In one embodiment, the present invention may replace a traditional paper ticketing system and improve efficiency by regulating admittance to an access-controlled venue with the reusable authentication device. An authentication device of such a system preferably includes a display for providing information, including that which might be found on a traditional paper ticket and/or ticket stub.
