Patent abstract
Embodiments of the present invention provide time-varying barcodes for information exchange. Specifically, embodiments of the present invention provide a system and method for communicating information between electronic devices via a time-varying barcode image sequence. In a typical embodiment, information to be transmitted is divided into packets. A barcode image is generated from each packet. Each barcode image is displayed sequentially with varying display times based on the complexity of the barcode image. A second electronic device reads and decodes the barcode image sequence until the entire information is received.
