Abstract: A system and method for creating and retrieving coupons using an electronic coupon database includes registering coupons with the database by a vendor, and then registering cell phones, also with the database; so that cell phones subsequently can request coupons from the database. The coupons are encrypted and sent to the requesting registered cell phone, which then decrypts the coupons for display and redemption at a point of sale. Provision is made to prevent the transfer of coupons from the requesting cell phone to some other cell phone in the system.

Abstract: A translator is provided for reading the bar codes displayed on the screen of a portable electronic device which utilizes a digital camera and/or a microphone responsive to tones from the portable electronic device to process and convert the information received from the camera and/or the microphone to a form readable by a reflective bar code reader without requiring any modification of the bar code reader.
