Twitter, AmEx to Let You Pay with Hashtag

It’s one small step for Twitter, one huge leap for social media. The online social-networking site announced plans to allow its customers to purchase products online in two steps, both of which are as simple as tweeting a hashtag. The plan—a collaboration between Twitter and American Express—will direct members who sign up to buy items in two quick steps. The first, by tweeting an @AmexSync hashtag, the second, waiting for a confirmation hashtag from AmEx itself. Customers must then simply tweet out the confirmation hashtag, and sold! AmEx sends an email to confirm within 15 minutes, and your brand new lime-green Crocs are suddenly en route. Products will be available beginning Wednesday morning.
