The value associated with the card can be accessed using a magnetic stripe embedded in the card, on which the card number is encoded; using radio-frequency identification ( RFID); or by entering a code number, printed on the card, into a telephone or other numeric keypad.
Typical applications of stored-value cards include:
Transit system "farecards"; Gift cards; Telephone prepaid calling cards.
Transit system farecards are popular with passengers because they eliminate the need to fumble with money when entering (or exiting) buses, subway trains, etc.
Many transit system operators have implemented farecards because they can accurately track system usage; they are useful for charging different fares depending on the distance traveled; they can automatically discount fares for seniors and persons with disabilities; and passengers can in some cases replace them if they are lost, stolen, or damaged.
Gift cards have all but replaced gift certificates, can be purchased in various values, and are good at various shopping, dining, and entertainment establishments. They are usually anonymous and no refund is available if they are lost or stolen. Also, issuers profit from the interest or float that is earned between the time of purchase and the time of use. Gift cards are sometimes refered to as "Closed Loop" cards in the business as they can only be used at the merchant who issued it.
A Store Value Credit Card is similar to a gift card. They feature a credit card logo such as Visa or Mastercard and can, unlike gift cards, be used anywhere a Visa or Mastercard me be used. They are very similar to a debit or check card except that they don't require a checking account to be issued one. They have been heavally marketed as a safe and responsible means for parents to give their children some spending power which is why they sometimes are referred to as teen cards. "Closed Loop" card is a term sometimes used to describe them in the business.
