A scannable coupon, such as a bar code, is generated on a configurable display of a portable electronic device, such as a personal digital assistant, handheld computer, or mobile telephone. The display has sufficient resolution and contrast to be scanned at a point-of-sale computer for redemption of the coupon. In a further embodiment, generic coupon information is sent to the portable electronic device, which can generate a scannable coupon in any one of several formats. In another embodiment, coupon information is sent in one format and the portable electronic device converts it to another format. In yet a further embodiment, a number of coupons are stored in a data structure according to a redemption characteristic, and may be serially displayed according to user input, such as pushing a step key.

What is claimed is: 1. A configurable portable electronic communication device comprising: a receiver configured to receive a wireless transmission containing coupon information; a processor electronically coupled to the receiver; a persistent dot-matrix liquid crystal display having a minimum nominal dimension of less than or equal to about 13 mils and an inter-pixel spacing of less than or equal to about 1.3 mils coupled to the processor; a memory containing a computer-readable program, the processor reading the computer-readable program to generate a scannable coupon code from the coupon information on the electronic display. 2. A configurable portable electronic communication device comprising: a receiver configured to receive an electronic wireless transmission containing coupon information; a processor electronically coupled to the receiver; an electronic display coupled to the processor, the electronic display having a nominal minimum dimension of less than about 13 mils and an inter-pixel spacing of less than about 1.3 mils; a memory containing a computer-readable program for generating a scannable coupon on the electronic display of the configurable portable electronic communication device from the coupon information and including instructions for converting the scannable coupon from a first scannable barcode format to a second scannable barcode format. 3. The configurable portable electronic communication device of claim 2 wherein the memory further contains a data file storing coupon information. 4. The configurable portable electronic communication device of claim 3 wherein the data file includes a plurality of subfiles, at least one of the plurality of subfiles containing a plurality of coupon data fields, each of the coupon data fields in the subfile being related according to redemption. 5. The configurable portable electronic communication device of claim 3 wherein the coupon information is encrypted and the computer-readable program contains instructions executable by the processor to decrypt the coupon information. 6. The configurable portable electronic communication device of claim 2 wherein the electronic display is a dot-matrix liquid crystal display having pixels capable of maintaining a contrast ratio of at least 1:4 between a light portion of a bar code and a dark portion of a bar code displayed on the electronic display between a first strobe signal and a second strobe signal to the pixels. 7. The configurable portable electronic communication device of claim 2 further comprising means for improving the first scan rate of the scannable coupon from the electronic display of the configurable portable electronic communication device. 8. The configurable portable electronic communication device of claim 7 wherein the means for improving the first scan rate comprises a contrast-enhancing coating disposed on the electronic display. 9. The configurable portable electronic communication device of claim 8 wherein the contrast-enhancing coating comprises an anti-reflective coating. 10. The configurable portable electronic communication device of claim 7 wherein the electronic display is a dot-matrix liquid crystal display and the means for improving the first scan rate comprises having a strobe rate of the dot-matrix liquid crystal display sufficiently high to maintain sufficient contrast for electronic scanning of the scannable coupon shown on the dot-matrix liquid crystal display. 11. The configurable portable electronic communication device of claim 7 wherein the means for improving the first scan rate comprises a liquid crystal display having sufficient persistence to maintain sufficient contrast for electronic scanning of the scannable coupon shown on the liquid crystal display.
