Therefore an analysis is carried out on how to make the image the content of the information contained in the QR Code. The solution offered is to convert the text into another representation that can be understood by the QR Code generator and QR Code reader. Previously, the text file was converted into binary.This research also generates QR Code Generator and QR Code Reader, where the input data is in the form of text, then tested to be applied in the real world.
