Final answer:
The QR code carries information in four directions: up, down, left, and right.
Step-by-step explanation:
The QR code carries information in four directions: up, down, left, and right. Each module in the QR code can be read in any of these four directions. This allows the QR code to hold more information compared to a traditional barcode, which can only be read horizontally. For example, if you rotate a QR code 90 degrees, it can still be scanned and the information will be interpreted correctly.
