FINANCIAL SERVICES FIRM American Express is working with Twitter on a payment system that will let people spend money with short messages.
It's called Amex Sync and requires that you synchronise an American Express card with your Twitter account. A video produced by American Express shows a brief walkthrough of how it works.
If you are in the US and want in then you must go to sync.americanexpress.com/twitter, and perform the necessary steps.
Doing this enters you into a world where tweeting a hashtagged keyword will make your Twitter account contact your American Express card account and make a purchase.
You can pick up items in retail stores or arrange for them to be delivered to your home.
It should go without saying that those involved are excited. "Based on the initial success of Amex Sync for offers, we know there is significant power in combining our assets with Twitter's platform to bring value to Cardmembers and merchants," said Leslie Berland, SVP of Digital Partnerships and Development at American Express.
"Now, we're leveraging our unique technology and closed-loop network to introduce a seamless solution that redefines what's possible in the world of social commerce."
The arrangement launched with some tweeted buying opportunities, including an Xbox 360 controller for $29.99 plus tax and an Amazon Kindle Fire HD for $149.99 plus tax.
Last week Twitter was the scene of a security attack that targeted 250,000 people, and included people like US president Barack Obama.
This week, when the firm added a Lolcat setting to its languages, some users responded with the request that it work on adding two-factor user authentication as well.
American Express told us that it has no plans for a UK rollout. µ
