A sales data processing apparatus which registers and processes sales data on a transaction-by-transaction basis. The apparatus includes: an imaging module that images manipulation situations successively; a recording module that successively records manipulation images taken by the imaging module; a journal storage module that successively stores and manages manipulation data of respective manipulations as journal data; a reproducing module that performs a reproduction operation of successively reading and displaying the manipulation images recorded by the recording module; a detecting module that detects timing of occurrence of a prescribed caution-needed manipulation by successively referring to contents of the journal storage module in link with the reproduction operation of the reproducing module; and a display control module that displays prescribed alerting data in association with a manipulation image at the timing of occurrence, detected by the detecting module, of the prescribed caution-needed manipulation.

Sales data processing apparatus, sales data processing system, and computer-readable storage medium

Disclosed is a wireless communication system including: a controller and a plurality of communication terminals connected to each other for communication, and the controller includes: a first wireless communication section; a communication number control section which counts a communication number of each of the communication terminal communicated and stores the number in the storage section; and a first communication control section which sets back off information indicating priority of communication of the communication terminal according to the communication number stored in the storage section and transmits the back off information through the first wireless communication section to the communication terminal, and the communication terminal includes: a second wireless communication section; and a second communication control section which sets the back off time of communication with the controller shorter as the priority becomes higher based on the back off information received from the controller.
