Abstract
To control access to a predetermined service or area, a system receives an activation signal indicative of a user's activation of an access code. As a result of receiving the activation signal, the system sends a verification code to a portable electronic device of the user. An access terminal receives the verification code. Access to the predetermined service or area is granted if the verification code is received at the access terminal meeting one of several predetermined conditions. One condition requires that the verification code is provided to the access terminal within a limited validity time.
