Advantages and disadvantages of debit card

Advantages of debit cards

•           A consumer who is not credit worthy and may find it difficult or impossible to obtain a credit card can more easily obtain a debit card, allowing him/her to make plastic transactions. For example, legislation often prevents minors from taking out debt, which includes the use of a credit card, but not online debit card transactions. Research has shown that consumers with lower credit scores use debit cards more intensively than those with higher credit scores.[7]

•           For most transactions, a check card can be used to avoid check writing altogether. Check cards debit funds from the user’s account on the spot, thereby finalizing the transaction at the time of purchase, and bypassing the requirement to pay a credit card bill at a later date, or to write an insecure check, containing the account holder’s personal information.

•           Like credit cards, debit cards are accepted by merchants with less identification and scrutiny than personal checks, thereby making transactions quicker and less intrusive. Unlike personal checks, merchants generally do not believe that a payment via a debit card may be later dishonored.

•           Unlike a credit card, which charges higher fees and interest rates when a cash advance is obtained, a debit card may be used to obtain cash from an ATM or a PIN-based transaction at no extra charge, other than a foreign ATM fee.

Disadvantages of debit cards

•           Use of a debit card is not usually limited to the existing funds in the account to which it is linked, most banks allow a certain threshold over the available bank balance which can cause overdraft fees if the user's transaction does not reflect available balance. This disadvantage has lessened in the United States with the requirement that an issuer obtain opt-in permission in advance to allow an overdraft on a debit card. Lacking this opt-in, overdrafts are not permitted for electronic transactions.

•           Many banks are now charging over-limit fees or non-sufficient funds fees based upon pre-authorizations, and even attempted but refused transactions by the merchant (some of which may be unknown until later discovery by account holder).

•           Many merchants mistakenly believe that amounts owed can be "taken" from a customer's account after a debit card (or number) has been presented, without agreement as to date, payee name, amount and currency, thus causing penalty fees for overdrafts, over-the-limit, amounts not available causing further rejections or overdrafts, and rejected transactions by some banks.

•           In some countries debit cards offer lower levels of security protection than credit cards.Theft of the users PIN using skimming devices can be accomplished much easier with a PIN input than with a signature-based credit transaction. However, theft of users' PIN codes using skimming devices can be equally easily accomplished with a debit transaction PIN input, as with a credit transaction PIN input, and theft using a signature-based credit transaction is equally easy as theft using a signature-based debit transaction.
