(Reuters) - Visa Inc
The talks, which began when Visa approached Visa Europe, are at an early stage and could fall apart if the two sides cannot agree on a price, Bloomberg said.
Visa's shares were up 4 percent at $69.29 on the New York Stock Exchange on Friday.
The range being discussed is $15 billion-$20 billion and both companies are working with advisers, Bloomberg said.
Visa said last year it might have to pay more than $10 billion to buy its London-based European licensee, Visa Europe, if the owners exercised their option to sell it.
Visa Europe, which since 2007 has operated independently of Visa, is a cooperative of more than 3,700 European banks with more than 500 million cards in circulation.
