Discover acceptance has historically been lower than Visa/Mastercard but has expanded significantly; acceptance is now comparable at most US merchants. The Discover Cashback Debit is notable for offering debit card cashback rewards, unusual after the Durbin cap limited debit interchange at large banks.
