Abstract
Systems and methods are described that use tag authentication and presence verification techniques in connection with a variety of transactions. In certain embodiments, an authentication device may verify the authenticity of a secure tag by determining whether the secure tag stores secret information provisioned by a trusted authority. In some embodiments, such an authentication process may be performed without exposing the secret information to the authentication device, thereby maintaining integrity of the secure tag. In other embodiments, insecure tags and/or tags that do not include secret information are used.
