American Express has launched the first ‘pay by tweet’ service on Twitter; it is a service that will allow Amex account holders to buy products simply by sending a short message.

What is Pay by Tweet?

The procedure is simple; once you link your Twitter and Amex accounts via the financial services firm’s app you will be able to accept offers from merchants by tweeting a hashtag included with the offer. Provided you tweet a confirmation within 15 mins to a follow-up message from Amex, they would forward your details to the merchant and complete the transaction.

Leslie Berland, head of digital partnerships and development at the payments company, said Twitter itself would not share in any of the transaction revenue from the Amex transactions.
