Abstract
A method and apparatus for providing access to an electrically controlled service for perdetermined periods of time employs a dual magnetically striped record medium encoded in a CRB format with data indicative of the periods of time during which access is to be provided. The data is read by a reader and stored in a processor having an internal clock and a comparator for comparing the instantaneous time output of the clock with the predetermined time period data encoded on the record medium for enabling a security device only when the instantaneous time is within the predetermined time period.
