One of the main features of each supermarket is the price label. It is a bearer of the basic information to the buyer and with it starts the buying process. At that point appear some of the problems for the sellers, especially when is needed everyday change of prices and also for the sectors for short shelf life products such as fruits and vegetables, meat, cheese, cooked food. As for the big super and hypermarkets when has to be created attractive price policy – promotions, happy hour, evening hour, etc. For some products prices have to be changed several times a day, and when not changed on time price difference between the label and check outs can occur. This can create conflicts that can affect the reputation of the company. By developing new technologies , DIGI has found a solution to this problem with electronic price labels – E-label, InfoTag and InfoCard.
