Twitter introduces pay-by-tweet service

The “Amex Sync” integration allows users who sync their Amex cards with Twitter to buy selected items by including special hashtags.

American Express first launched its original Twitter Sync feature last year, which allowed customers to get discount deals by tweeting hashtags of special offers. Now it has extended the feature to allow payments.
This new arrangement aimed at providing a new source of financing for Twitter, which has so far been largely reliant on advertising revenue.

Understandably, neither Amex nor Twitter will discuss financial terms of their partnership, but Twitter doesn’t rule out taking a cut of future e-commerce sales.

“We’re convinced that commerce is going to be one of the areas (for which) advertisers are going to start using our platform,” Joel Lunenfeld, Twitter’s vice president of global brand strategy, told the Wall Street Journal.
