About this subject

Card terminals, also known as Point of Sale (POS) devices, are electronic equipment that process payments via credit, debit, and increasingly, contactless (NFC) cards. In Brazil, their use has grown exponentially since the 2000s, driven by the popularization of cards and the shift from cash to electronic means. According to the Brazilian Association of Credit Card and Services Companies (Abecs), the volume of card transactions in the country reached R$ 3.3 trillion in 2022, with debit and installment credit leading.

The small screen, typically LCD or LED, displays essential information such as amount, payment method, and transaction status. When approved, a message like "Approved" or "Transaction authorized" appears, followed by the option to print a receipt. On overcast days, ambient lighting reduces reflected glare, making the screen easier to read. Modern terminals, such as those from Rede, Cielo, and GetNet, feature 3G/4G, Wi-Fi, and Bluetooth connectivity, enabling operation anywhere from street markets to restaurants.

Security is a critical aspect. Terminals use end-to-end encryption and tokenization to protect sensitive data like card numbers and PINs. In Brazil, the adoption of EMV chip technology (Europay, Mastercard, Visa) drastically reduced in-person fraud. Contactless technology, allowing tap-to-pay, made transactions faster and more hygienic, especially after the COVID-19 pandemic. By 2023, over 60% of terminals in the country were estimated to accept contactless payments.

Interestingly, Brazil is one of the largest card terminal markets globally, with over 10 million active devices. Competition among acquirers led to lower fees and zero-cost machines for small merchants. The card terminal became a symbol of financial inclusion, enabling street vendors and individual micro-entrepreneurs (MEIs) to accept electronic payments, once limited to formal establishments.
