Data Transmission to Mobile Devices via Multiple QR Codes

Data transmission to mobile devices can be done easily with the use of Bluetooth and Wi-Fi, but these methods have weaknesses such as the significant amount of time needed for the device search and authentication phase when transmitting small amounts of data. Previous works proposes transmitting data via multiple high capacity two-dimensional barcodes, which works as a partial solution but still has certain aspects that can be improved. In this paper, we propose a system for transmitting data via multiple QR codes that aims to maximize the overall data transmission rate by maximizing read accuracy and code processing speed. We also test the use of RaptorQ fountain code to improve handling of missed frames in the system. Analysis and tests done on the system proves that the proposed system can be reasonably used as an alternative data transmission method when transmitting files up to 500KB in size or when other data transmission methods are unavailable.
