QR code is now very commonly seen everywhere in different fields. While barcode has been existed and applied into life long time too. For your question, I'm not sure which type you should choose. You see, barcode is not only one type, it has more than dozen of symbologies, including 1D(code 128, EAN 128, UPC-A/E,etc) and 2D(PDF-417, data matrix, QR code). Each one of them has its own advantages and disadvantage. So which one to choose depends on you program and the data you wanna encode.
