Thats why QR code scanning will be much cheaper. All one need is placing one ad in newspaper or magazine(with QR code) or in grocery stores, fast food chains, or bill board, or behind vehicle. It will be cheaper than mail/postage stamps.
Its only a matter of ones eye noticing the QR code, once done they only need to scan it once using smart phone.

Anyway just an idea/thought if its too late or this will also prove expensive then just ignore it.
