Do you understand your rates? Likely you do not! Merchant Credit Card Discount Rates have changed; no longer can a rate of 1.65% be considered a low cost rate. Visa & Mastercard have re-structured the card industry with the introduction of specialty cards, such as Visa Infinite, Cash Back, Premium, Preferred, Corporate, Aeroplan and other Points cards. Mastercard, more so than Visa, supports specialty cards, High Spend, Premium High Spend and World Cards. These cards cost the Banks that issue them more than a plain Visa or Mastercard. To support the extra cost, both organizations have added an “Interchange Differential” or “Downgrade” or “Surcharge” to transactions when these cards are used. In short, merchants pay more to accept these cards.
