I will be doing door to door cold calling and dropping of my business card. I need something to make my business card to stand out.

Whilst doing research on Google, I came across a suggestion to put something like a calandar on the back, to make the card sticky. I first thought of putting the school holidayts or public holidays. But would people use it simply to look up the holidays and not bother wit the front of the card?

My next idea was to put a QR code on either the front or back of my card, which points to a Mobi ready page with discount coupons & specials for my services, maybe invite some of my customers to add their discount coupons and specials.

When droping off the card, I would point out that by using the QR/Bar Code reader on their smart phone would take them to the specials.

Any suggestions would be appreciated.
