Redemption® will work at any merchant where magnetic stripe readers are used. The face of the device is printed with a single credit account number and includes two buttons with associated light sources. A user can choose whether to use points or use credit at the point of sale by pressing the appropriate button. The card will then visually indicate the selection by turning ON the light source associated with the selected option. The magnetic-stripe information associated with the payment option is then written to the Electronic Stripe®.
