Visa is an electronic payment brand offered by the Visa Inc. Company, an American international financial services corporation. The company is headquartered in Foster City in California. Chiefly, it facilitates electronic funds transfer via Visa-branded prepaid cards, debit cards, and credit cards.
The company does not issue cards, set rates, or extend credit to consumers. Instead, it offers financial institutions payment products under their brand name. The financial institutions can then use the payment product to provide customers with debit, credit, and cash access.
Currently, almost all Visa transactions are made via VisaNet at any of four data centers. The data centers are located in Virginia, Colorado, England, and Singapore. The data centers operate independently, each capable of handling up to 30000 simultaneous transactions.
