What is a POS Terminal?
A POS terminal refers to the hardware used to accept and process payment transactions. Traditional cash registers were once considered the primary tool for sales completion. However, POS terminals now encompass a range of advanced capabilities, including card payments, barcode scanning, receipt printing, inventory monitoring, and even integration with business analytics tools.
At the heart of the terminal is its ability to connect with payment gateways that validate credit or debit card information, ensuring sufficient funds and completing transactions securely. Once verified, the payment is processed, and a receipt is generated either as a physical printout or sent digitally via SMS or email.
How POS Terminals Work
The typical POS transaction follows a straightforward process:
- The total purchase amount is calculated using POS software.
- A customer swipes, inserts, or taps their card on the POS terminal.
- The terminal reads the card data and securely sends it through the payment gateway.
- Card networks authorize the transaction in real time.
- An authorization message is returned, and the sale is completed.
- A receipt is printed or shared electronically.
POS systems have gradually shifted from proprietary hardware to mobile-based platforms, leveraging tablets and smartphones. These mobile POS systems (mPOS) are flexible, portable, and cost-effective. They are especially valuable in environments where speed and mobility are crucial, such as restaurants, delivery services, and trade fairs.
