What is a QR codeA QR code (2-dimensional bar code) is a black-and-white graphic that distributes data symbols in a plane (two-dimensional direction) by a certain geometry.In many kinds of two-dimensional barcode, the commonly used code system is: Data Matrix, Maxi code, Aztec, QR
used as the data source. However, subsequent integration with existing software should not be a problem, because db4o can directly store feature objects and geometry objects. However, the dependence of the generated data on the implementation is another problem: the data is closely coupled with the implementation, and the code is bound to the data, although db4o claims to support Java and. but it becomes a problem for other implementations.From this
