Abstract: A system for managing containers includes a server, a portable electronic device and a check apparatus. The server stores a piece of transaction data. The portable electronic device is configured to receive the piece of transaction data from the server, to determine whether a shaking criterion is met based on acceleration of the portable electronic device, and to display a barcode corresponding to the piece of transaction data when the shaking criterion is met. The portable electronic device is further configured to capture an image and send the image to the server. The check apparatus is configured to read and decode the barcode, and to display information relating to the piece of transaction data based on data encoded in the barcode.
