With New way of QR code system, A2A Digital brings you to another level of using digital key or “QR Code” instead of physical key. The QR code stands out with its three small squares placed in the lower and upper left corners and upper right corner. The overall code has a square shape composed of a matrix of small squares. The fewer squares, the less information the code contains and vice versa for more squares. Because information is contained in two directions, it can hold a lot more data than a one-dimensional barcode.
