Abstract
A payment card is provided with a display. A barcode may be selectively displayed on the display. A display may be an electrochromic display in order to increase the readability of a displayed barcode with respect to computer vision equipment. A barcode may be selected by a user from a set of barcodes. Each barcode in a set of barcodes may correspond to a different loyalty account for a different merchant. Accordingly, a user can carry a single card—but may be able to communicate multiple loyalty account barcodes to computer vision equipment across multiple merchants.
