Quick Response codes put name cards in the fast lane

When Huo Chunhua from Suzhou, Jiangsu province, hands out his new business cards, people are surprised to see a small black-and-white square on the card, with his micro-blog avatar within it.

They follow his request to use a smartphone's camera to scan the square grid, and his basic information such as mobile number, e-mail, and company name soon pops up in the phone.

Such magical Quick Response-coded name cards are becoming more popular recently, both for their convenience and fresh design.
