Google mails 2D barcodes to local businesses

Would I rather a potential customer typed in my URL and got my "story" or would I let them scan a QRcode that takes them to Google and its links to reviews, competitors etc?
Might businesses also have legitmiate concerns that this is Google getting even more information about the customers (and that this might become yet another Google revenue stream down the track)?
Businesses can claim their identity at Google and modify information about them (hours, phone # etc.) I don't think you can control what reviews appear though.
Google might just have broken that barrier by mailing out 150,000 QRcodes.
