About this subject

Card terminals, also known as POS (Point of Sale) devices, are electronic devices essential for processing payments with credit, debit, or voucher cards. In Brazil, their mass adoption occurred from the 2000s onwards, driven by the popularization of cards and the modernization of the financial system. Today, these terminals are common in commercial establishments of all sizes, from large retail chains to small street vendors.

The screen displaying "approved transaction" indicates that the payment was authorized by the card brand and the issuing bank, releasing the amount to the merchant. This process takes only a few seconds, thanks to real-time communication with financial institutions. Approval depends on factors such as available balance, credit limit, and any security blocks.

On overcast days, ambient light can interfere with screen readability, especially in older models with LCD displays. Therefore, many modern terminals feature high-contrast screens or automatic brightness adjustment. The scene depicts a common moment in the daily life of Brazilian consumers, who carry out electronic transactions even in adverse weather conditions.

Interestingly, Brazil is one of the world leaders in electronic payments, with over 80% of transactions made by card or mobile devices. The popularization of PIX in 2020 reduced the use of cards in some segments, but terminals are still ubiquitous, especially in physical retail.
