AddressVision's free mobile application - IMBscan - provides a very easy way of decoding postal barcodes. After launching the app and pressing the Start button, simply aim your iPhone's camera at the barcode, align the red line over the barcode and hold still for a couple of seconds. As soon as IMBScan obtains a positive read from the barcode it will automatically display the ZIP code and address. It is that simple! (Note: If your iPhone does not have access to the Internet, the street address information will not be displayed)
