Visa is looking to take on Silicon Valley payments companies like PayPal and is turning to developers to jumpstart its efforts.<br />Right now, Visa Developer consists of more than 150 application program interfaces that enable everything from fraud prevention, mobile checkouts and person-to-person payments.<br />Visa CEO Charlie Scharf said the initiative would help the credit card company bridge the gap between physical payments and digital payments. "<br />Even though Visa is entering into the space much later than its other Silicon Valley-based rivals, the company says it has an advantage over other companies because of its extensive network of partners, including thousands of banks and other financial institutions.
