Point of sale (POS) is the place where a transaction occurs in exchange for goods or services. The point of sale often refers to the physical electronic cash register or dedicated POS hardware used for checkout,

For SMB retailers, UDTX offers an inexpensive, versatile and secure method to charge the customer while keeping full control over every element of the transaction.

POS will be customized by retail industry as different industries have different needs. For example, a grocery or candy store will need a scale at the point of sale, while bars and restaurants will need to customize the item sold when a customer has a special meal or drink request. UDTX POS implementations will also include advanced functionalities to cater to different verticals, such as inventory, CRM, financials, warehousing, and so on, all built into the POS software. Prior to the modern POS, all of these functions were done independently and required the manual re-keying of information, which resulted in a lot of errors.
