POS Duo is an application designed to simplify and improve the shopping experience for both customers and sellers, and has a user-friendly and easy-to-use interface.

The main objective of POS Duo is to offer an efficient and intuitive solution for checking items during the purchasing process. It works in conjunction with a tablet, which acts as a digital mirror of the traditional point of sale. When a customer makes a purchase and the items are registered in the point of sale system, POS Duo replicates these items in real time on the tablet, providing a clear and detailed view of the products purchased.

This functionality is especially useful for customers as it allows them to easily track the items being added to their purchase, checking the accuracy and quantity of selected products. With POS Duo, customers have the opportunity to review their purchase instantly, avoiding errors and ensuring a more transparent and satisfactory shopping experience.
