Abstract
A validation phase is performed at an RFID reader, in order to ascertain which of a plurality of potential candidates for authentication, are actual candidates for authentication. Once a candidate has been successfully validated, an authentication phase is initiated with a host computer, to determine whether the information presented by the candidate matches expected information about the candidate. If the authentication is considered successful, a final authorization procedure may be performed, or the authenticated candidate may be granted certain predetermined permissions. By performing the validation phase locally at the reader, the need for accessing a host computer is reduced and unnecessary queries to the host computer are avoided.
