I dont think visa credit cards are that common?
@HeatingOnHeatingOff Visa are absolutely huge!
Visa is the largest credit card issuer in the United States. According to CreditCards.com data, Visa has 304 million cards in circulation in the US and 545 million cards in circulation outside the US. Total transaction volume in the US was $1.2 trillion USD in 2014.
Mastercard has 191 million cards in circulation in the US and 576 million cards in circulation outside the US, which actually places it ahead of Visa globally (excluding US). However, US transaction volume is only $607 billion, around half of Visa’s total.
