The European Commission, which acts as the 27-nation bloc's competition watchdog, says Visa proposes to reduce its inter-bank fees for credit card payments to 0.3 percent of a transaction's value a reduction of about 40 to 60 percent.
It says the company is also proposing to reform its rules to facilitate cross-border competition.
The Commission said last year Visa's fees and rules reduce price competition between banks, inflate the cost of payment card acceptance for merchants and ultimately increase consumer prices.
