Definitions

  • the invention relates to a method for monitoring and / or controlling a purchase process in a retail store.
  • the invention further relates to an arrangement for carrying out this method.
  • the invention relates to a mobile data peripheral device to be carried by a store customer, a central control unit, and a data peripheral device available to at least one store user, all of which are adapted for use in such an arrangement.
  • the invention also relates to a computer program product, a machine-readable, in particular computer-readable, data structure and a machine-readable, in particular computer-readable, data carrier with program parts for carrying out the method.
  • Retailers especially in self-service shops in the food trade, use checkout systems and methods for their use which involve reading a product code, spread in the form of a bar code, products selected by a customer for purchase, and a checkout process by cashiers at a cash register Store is performed.
  • the payment process takes place.
  • This procedure causes the retailers corresponding material costs for the acquisition of the cash register systems and personnel costs for the import and payment process. These costs can not be flexibly adjusted to the same scale as the number of customers over time, eg the time of day or opening hours of the shop, varies. For example, during times of strong customer demand make long queues in front of the cash register because not enough staff and / or funds are available. The formation of these queues leads to inconvenience for the customers, which can ultimately cause loss of revenue. On the other hand, it may happen, for example, that during periods of low customer traffic, the available funds are not utilized, ie in these times the corresponding material and possibly personnel costs are not matched by sales, so that the profitability of the trading company deteriorates.
  • the US 2015/0051994 A1 discloses a shopping system that allows users to select items before shopping, for example, online, where a shopping list is stored by the system, which system directs a user to a self-service checkout if the user does not prepay some or all items online in advance Has.
  • a shopping list is stored by the system, which system directs a user to a self-service checkout if the user does not prepay some or all items online in advance Has.
  • stationary retail which ensures low waiting times for the end customer and low costs for the retailer, especially if one compares the possibilities in online trading.
  • Online payment methods known from the prior art can not be used in stationary retailing in self-service shops, since there is no assurance that the end customer will pay for his goods in full, in particular. Technologies using RFID transmitters and receivers are not practical or economical, especially in food retailing, due to excessive costs relative to low margins.
  • the object of the invention is to provide a method and an arrangement for monitoring and / or controlling a purchase transaction in a retail store, by means of which personnel and / or material costs can be reduced without increasing the risk of theft or inconvenience for the customers.
