BACKGROUND
1. Technical Field
Apparatuses and methods consistent with the present inventive concept relate to point-or-sale operations, and more particularly to systems and methods for self-service or assisted customer check-out and inventory monitoring.
2. Related Art
A point of sale is the place where a retail transaction is completed, for example, a check out area in a retail store at which a customer makes a payment to the merchant in exchange for goods or services. At the point of sale, an amount due from the customer for the goods or services to be purchase is calculated, options for payment are provided, and a receipt for the transaction is issued. Typical point of sale areas provide dedicated terminals for attended (i.e., cashier-assisted) checkout and/or dedicated terminals for self-service checkout, thereby lacking flexibility of use.
In addition, inventory management presents a challenge for businesses. Efficient inventory management requires oversight of the continuous flow of product into and out of an existing inventory. Managing inventory typically requires one or more employees to dedicate time to physically locate and count product on hand, generate inventory reports, place purchase orders to replenish stock, and track the orders.

Value may also be added to a stored value card via the stored value card recharge unit 147 at the stored value card station 140. In an example embodiment, an employee badge may be used in an on-site company cafeteria as a secure and unique method of identification to access a stored value account and make payments. Value may also be added to a stored value card via a wireless connection to the stored value card recharge unit 147 using a mobile device.
The point-of-sale system 100 may also support the ability to reconcile customer purchases across different point-of-sale system operators and different countries. In an example embodiment, value may be added to a stored value account at a point-of-sale system 100 in a first state and a purchase made at a point-of-sale system 100 in a second state with a stored value card associated to that stored value account. The point-of-sale system operator in the second state is paid by the point-of-sale system operator in the first state where payment was made to add value to the stored value card.
The point-of-sale system 100 may also collect detailed information about the buying patterns of customers, and may use that information to generate notifications that are sent to the customers to promote additional purchases of the same, similar, or alternative products.
In an example embodiment of the present inventive concept a point-of-sale system 100 may implement a loyalty program. The point-of-sale system operator may assign points to certain activities, for example, a high number of points may be given for purchasing expensive healthy items or for purchasing items during a specified time period. The loyalty points may then be redeemed for cash, prizes, or other items as determined by the point-of-sale system operator. The loyalty program may be tied to stored value accounts and may capture multiple balances in different sub-accounts. Different balances may be spent on different items. For example, a “healthy” account may be recharged when the customer buys healthy food or when they visit a gym or respond to a short survey. These stored value account balances may then be used to make purchases for healthy items.
One of ordinary skill in the art will appreciate that the above examples of loyalty programs are only non-limiting examples for illustrative purposes and that many other implementations are possible without departing from the scope of the present inventive concept.
