Card terminal showing approved transaction on small screen

Card terminal displays approved transaction on small screen, signaling completion of electronic payment in retail.

About this subject

Electronic payment terminals, also known as Point of Sale (POS) devices, have become ubiquitous in Brazilian retail. According to ABECS (Brazilian Association of Credit Card Companies), Brazil recorded over 30 billion card transactions in 2023, solidifying the country as one of the largest electronic payment markets globally. These terminals have evolved from simple magnetic stripe readers to modern devices with color screens, NFC (Near Field Communication) support, and 4G connectivity.

When a transaction is approved, the terminal issues a digital or printed receipt, and the screen displays the confirmation message, often accompanied by an audible beep. This immediate feedback is crucial for security and consumer confidence. In Brazil, contactless payments have grown exponentially, accounting for over 40% of in-person transactions in 2023, according to Visa.

Despite their small size, terminal screens are designed for readability under various lighting conditions and angles. Many newer models use IPS (In-Plane Switching) technology for better viewing. The interface is simplified to speed up service: messages like "Transaction Approved" or "Approved" are highlighted, often in green, a color associated with success and security.

Interestingly, the first card terminal in Brazil was installed in 1978, but widespread adoption began in the 2000s with lower costs and credit expansion. Today, even small informal traders, such as market vendors and street sellers, use devices from companies like Stone, PagSeguro, and SumUp, which have turned smartphones into payment terminals.

Why is the card terminal screen small?

The small size is for portability and low cost. However, modern screens use IPS technology to ensure readability and contrast in different environments.

Do all card terminals in Brazil accept contactless payments?
