Also, in order to scan the code, the smartphone must be placed close to the code in order to work correctly. Unscannable codes can kill and delay the adoption rate for 2D bar code campaigns. QR codes for billboard or bus campaigns are not practical because users will have difficulty scanning.
Because the idea is relatively new in the U.S., no one at the table had hard and fast evidence about QR code return on investment. 2-D bar codes have been popular in Asia for over a decade, originally designed by a Japanese company to read at a quicker speed than conventional barcodes.
