As part of their “Free Stuff” issue, Allure is giving away a crapload of beauty swag. The August issue is on sale now but the contest doesn’t start until the first weekday in August (8/2/10).

That’s 159 different giveaways of 32,358 products. Participants will get the chance to win a range of products from Giorgio Armani perfume ($39.50), to Lancome skin care ($155), to a Calvin Klein bag ($850).

Readers can enter the giveaways using Microsoft Tags–2-D bar codes that are scan-able by smart phone. The beauty mag will publish 36 “Tags” that can be ripped out and scanned for a chance to win at anytime.

I only just figured out how to add new bbm contacts using my phone’s barcode. So this seems way over my head. But those kids with the technology–they pick up quick. Allure could be on to something here. Everyone’s got a smart phone these days.

“When done right, technology is a service, not a gimmick,” says Allure editor Linda Wells in a press release. “Our readers no longer have to be tethered to their computers to enter to win Free Stuff.”

Would you be more likely to enter a giveaway if you could scan in to win through your phone?
