Card Payments
Card payments refer to the technology and infrastructure that enables electronic transactions using payment cards, such as credit, debit, or prepaid cards, typically processed through networks like Visa, Mastercard, or American Express. It involves secure data transmission, authorization, and settlement between merchants, card issuers, and payment processors to facilitate online and in-person purchases. This includes compliance with standards like PCI DSS (Payment Card Industry Data Security Standard) to protect sensitive cardholder information.
Developers should learn card payments when building e-commerce platforms, mobile payment apps, or any application that requires handling financial transactions, as it is essential for enabling secure and reliable payment processing in digital products. This skill is critical for roles in fintech, retail tech, or any industry involving online sales, ensuring compliance with security regulations and integrating with payment gateways like Stripe or PayPal to streamline checkout experiences.
