Beer marketing with QR code
This beer glass lets you tweet about your pint and/or update your Facebook status while drinking it. Scan the QR code – and you check in to social media such as Facebook or Twitter. You need Guinness or a similar very dark beer to be able to scan the QR code.
If the glass is filled with an ordinary light pilsner, the QR code scanner will not be able to read the code.
What about adding several QR codes to the glass, allowing the codes to be scanned to show different results/landing pages depending on how much beer is left in the glass?
