Very low cost and no need for additional physical checkout, the system, dubbed Papa-Queue, works with APP Sambanet Papa Filas software. While the customer waits in line to pass their products through the checkout, an operator uses a wireless or cellular reader to check the codes of the products in the trolleys and baskets with the data transmitted to an ID card and stored in the system. With the delivery of the card at checkout, the consumer only makes payment. To implement the set, formed by the APP Sambanet Papa Fials, by camera phones or wifi collectors, there is no need for modifications in physical space.
