A point-of-sale solution allows a shopper to make a cashless in-store payment in a merchant's shop. This payment is usually made using cards, although some local methods (like Apple Pay or Android Pay) can be used as well.
Adyen provides its own POS service, including devices and infrastructure. Merchants that also accept payments online or in-app can use Adyen as their omnichannel payment solution. This gives them a single reporting dashboard, where they can view all purchases.
Often the term "point of sale" is used in place of "Cash register" to denote the software collecting POS payments.
