  • Inter-device data transfer based on barcodes
    Patent number: 9600701
    Abstract: A sending computing device encodes data items as barcodes and simultaneously displays two or more barcodes on a first display screen of, or operatively coupled to, the sending computing device. A receiving computing device obtains the two or more barcodes from a single video frame captured by a first camera module of, or operatively coupled to, the receiving computing device. Furthermore, the receiving computing device encodes, as an acknowledgement barcode, an acknowledgement that identifies each barcode that was successfully received and displays the acknowledgement barcode on a second display screen of, or operatively coupled to, the receiving computing device. The sending computing device captures the acknowledgement barcode via a second camera module of, or operatively coupled to, the sending computing device. Based on the acknowledgement barcode, the sending computing device determines which of the data items were or were not successfully received by the receiving computing device.
