Visa introduced number of changes to its Fixed Acquirer Network Fee (FANF) structure last year that will become effective on April 1, 2015 and July 15, 2015.  The changes impact payment aggregators like PayPal and Square, small merchants with less than $1,250 in monthly Visa sales volume and select merchants operating unattended terminals/kiosks.
