Card terminal showing approved transaction on small screen

Card terminal shows approved transaction at a Brazilian store, ensuring secure and fast payment.

About this subject

In Brazil, the use of card terminals (POS) has become ubiquitous in commerce, from large chains to small businesses. These devices, like the one in the image, process payments via contactless, chip, or magnetic stripe, displaying the transaction confirmation on the screen. The mass adoption of these terminals has boosted financial inclusion: according to Central Bank data, in 2023 there were over 12 million active POS machines in the country, a number that grows annually.

The "transaction approved" screen is a critical moment for the consumer, who seeks immediate visual confirmation. Modern terminals feature end-to-end encryption and tokenization, reducing fraud. Additionally, Central Bank regulations require the establishment to provide a receipt, either printed or digital, ensuring the right of withdrawal for purchases made outside the physical store.

Interestingly, Brazil is one of the largest electronic payment markets in the world, with over 80% of retail transactions made with cards. The popularization of contactless payment (NFC) accelerated this movement, especially after the pandemic, when physical contact was avoided. Today, even street vendors at fairs use portable terminals connected via cell phone chips.

The image shows a terminal with a compact design and long battery life, ideal for high-traffic establishments. The liquid crystal display (LCD) shows large, high-contrast characters for easy reading even under direct sunlight. For the merchant, the on-screen confirmation is the signal to release the product, while the system automatically records the sale in the management software.
