Encouragement Cards

Request to confirm the logic of incentives and discounts are offered only on credit cards and not debit cards. Infact debit cards should be more reliable and trustworthy. As airlines and even some shopkeepers always try to avoid or not to authorize purchases on a debit card. What are the advantages of a shopkeeper other than the card company in this transaction. Can we raise our voices against this discrimination?

Remember, the store pays a fee each time a card is used in their shop. Taxes on purchases by debit card are much more expensive than credit cards. So I do not blame them for encouraging the use of credit. Until you pay your credit bills in full each month, is this really matter to you anyway?
