The EndChain QR code is unique in that it incorporates a barcode within the QR code. This design allows for simplified use as EndChain users will know to scan the only code found on the packaging. Other businesses which rely on legacy barcode technology will be able to scan the embedded barcode. Thus, EndChains QR code creates a singular code to work on any type of system. An additional benefit is that the single code can update both the blockchain and any internal legacy systems with a single scan. The goal of this is to reduce complexity while increasing efficiency.
