I have been using the Nilson Report since I was first involved in cards in 1975. For 47 years, through credit card issuing, debit card launches, prepaid cards, merchant acquiring, and now crypto, Nilson has been my “go to” publication for industry facts for issuing, acquiring, and all elements in between. More important, Nilson just provides the facts – no spin, no politics, just the facts.
