Abstract: Techniques for making electronic cards that can be displayed on a mobile phone. The techniques permit making an electronic card based on an arbitrary SMS message and making an electronic card (eCard) that corresponds to a pre-existing non-electronic privilege card such as a loyalty card. In the latter case, the system on which the card is being made obtains information about the user and the issuer and uses the information to determine whether to issue the eCard and also to make use validity information which is associated with the card and is used to determine the validity of the card as it is used.

Abstract: Techniques for ensuring maximum readability of barcodes displayed in pixel displays. The techniques use the characteristics of the pixel display to determine the form of the barcode in the pixel display. Determination of the form includes determining a size of the barcode which renders the barcode's elements easily readable by a barcode reader and a shape, and or orientation of the barcode in the display which permits the entire barcode to be displayed in the display. Additionally, in a barcode with redundant information, the amount of redundant information may be reduced in the displayed barcode. The techniques may be applied to both one-dimensional and two-dimensional barcodes.
