American Express and Twitter recently announced a new deal that will let Twitter users purchase goods on the micro-social network.
American Express customers first need to sync their credit cards to their Twitter accounts. They can then tweet specific hashtags to buy American Express gift cards and products from Amazon, Urban Zen, and Xbox 360. AmericanExpress will reply via Twitter with a confirmation hashtag, and ask the user to confirm the purchase in a tweet.
Twitter could now potentially have a new source of revenue. Neither Twitter nor American Express are willing to discuss the financial terms of the partnership.
