Embodiments include a point of sale system. The point of sale system includes a base, a stand coupled to the base, and a head unit coupled to the stand. The point of sale system further includes two outer hinge arms and an inner hinge arm that couple the head unit to the stand.

A system and method of sourcing materials by connecting or matching Sellers having present or expected inventory with Buyers having present or expected necessity while minimizing or eliminating the use of a third party intermediary are disclosed. In some implementations, a method of sourcing materials may generally comprise receiving bid information from a candidate Seller and demand data from a candidate Buyer, comparing the bid information and the demand data to match a portion of the candidate Seller's inventory to the candidate Buyer's need (to identify a transaction), allocating and routing the portion of the inventory to the candidate Buyer via a transportation carrier, and augmenting the historical data with information associated with the transaction.

A checkout device in a point of sales (POS) system includes a table on which one or more merchandise items can be placed, a scale configured to measure a total weight of the merchandise items placed on the table, a scanner configured to read an image displayed on a terminal operated by a customer, and a processor. The processor is configured to, upon receipt of the image by the scanner, determine one or more merchandise items that have been registered by the customer using the terminal, determine a total weight of the registered merchandise items using a weight predetermined for each merchandise item, determine whether a difference between the determined total weight and the measured total weight exceeds a threshold, and upon determining that the difference exceeds the threshold, issue an abnormal command.

In some examples, a system and method for pairing a payment object reader with a point-of-sale (POS) terminal is described herein. The payment object reader includes one or more light indicators configured to display information in an optical pattern of one or more colors, brightness, lightness, and intensities, wherein the light indicators display a first optical pattern representative of an operational status of the payment object reader in a first mode, and a second optical pattern representative of a pairing code in a second mode. A display control component, executed by a processor, is configured to control the light indicators in accordance with the pairing code to generate the second optical pattern, the second optical pattern when shared with the POS terminal enables pairing between the payment object reader and the POS terminal. When paired, the payment object reader allows the POS terminal to accept payments from a customer.
