kaartidevõrkudes

Kaartidevõrkudes, meaning "card networks" in Estonian, refers to the interconnected systems that facilitate electronic payment transactions. These networks are essential for processing credit and debit card payments globally. Major card networks include Visa, Mastercard, American Express, and Discover. When a cardholder makes a purchase, the transaction information is sent through the merchant's acquiring bank to the relevant card network. The card network then routes this information to the cardholder's issuing bank for authorization. If approved, the issuing bank sends the approval back through the network, allowing the transaction to be completed.

These networks play a crucial role in ensuring the security and efficiency of electronic payments. They establish the rules and standards for card transactions, manage the flow of funds between financial institutions, and provide fraud detection and prevention services. The infrastructure of card networks involves complex technological systems that handle millions of transactions daily. Understanding kaartidevõrkudes is important for comprehending the modern financial landscape and the underlying mechanisms of digital commerce. The continued growth of e-commerce and contactless payments further emphasizes the significance of these global payment networks.
