Brick-and-Mortar Transaction

A Point of Sale (POS) in a brick-and-mortar store is the system where a customer completes a purchase and the business processes the payment. It includes both the physical hardwaresuch as cash registers, card readers, barcode scanners, and receipt printersand the software that manages transactions, inventory, customer data, and reporting. In merchant services, the POS acts as the central hub that connects payment processing technology with the stores daily operations.

How a POS Works in a Physical Store

When a customer is ready to buy, the POS system calculates the total cost, applies taxes or discounts, and processes the payment using the merchant service provider. The POS communicates with the payment processor to authorize the transaction, ensuring the customers card or digital wallet has sufficient funds. Once approved, the POS completes the sale, updates inventory, and records the transaction for reporting and accounting.

POS Hardware Components

A brick-and-mortar POS typically includes several physical devices:

The Role of Merchant Services in POS Systems

Merchant services connect the POS system to the financial networks that process payments. They ensure secure authorization, encryption, and settlement of transactions.

Together, the POS and merchant services create a seamless checkout experience for both the business and the customer.
