A simple data storage system using QR code

Due to its limited data area, QR codes are presently restricted to storing simple text messages. In this paper, we develop a novel method to expand the storage capacity of QR codes. We propose to compress the file first before encoding it into a QR code. Doing so, we would be able to store more complicated files which require more storage capacity. In our study, we show that both monochrome and colour image files, as well as, voice messages in midi format could be encoded to and decoded from the QR codes.
