appeal sets forth a step of operating the self-service
checkout terminal therein “so as to allow said customer to

terminal in response to generation of said audit-required
control signal,” that is, the customer himself or herself
performs a self-audit of the items involved in the retail

transaction, includes, inter alia, a self-service checkout
