Credit cards with chip: security technology in Brazil and worldwide.

About this subject

The chip in credit cards is a security technology used to protect financial transactions. Introduced in the 1990s, the chip is a microprocessor that stores confidential information, such as card numbers, expiration dates, and CVV. In Brazil, the use of chip-enabled credit cards became mandatory in 2014, in response to the growth of e-commerce and the need for greater security.

Globally, the adoption of chip-enabled credit cards is considered a security standard. According to the International Organization for Standardization (ISO), more than 90% of credit cards issued in 2020 featured this technology. However, the lack of chip-processing infrastructure in some countries still represents a challenge to the security of financial transactions.

The security of the chip is based on authentication criteria, such as the use of passwords and PINs, as well as verification measures, such as the validation of suspicious transactions. Additionally, the chip can store data on card owners, such as addresses and contacts, facilitating identification and treatment of potential security issues.
