Abstract
The invention provides a data display device and a system which display a sales amount or number of coins inserted into, for example, a game machine in a form not directly comprehensible to a person in order to prevent reading by an unauthorized person. This prevents dishonest acts or pilfering by the unauthorized person. This form, not directly comprehensible, can be a bar code. The unauthorized person can read the sales data only by a bar code reader, so he will have no way to know the sales amount to match with the actual collected amount of the coins.
