Transaction or receipt data, e.g., data of a receipt document, is encoded as a two-dimensional machine readable representation, such as a QR CODE. Certain receipt data is encoded as segments of a QR CODE. An image of the QR CODE is acquired using a camera of a mobile communication device or computer or other image capture device. The QR CODE image is decoded to determine the receipt data, and fields of an electronic receipt summary can be populated with decoded data. |
