Amex Sync on Twitter is the latest payment innovation by American Express (Amex): You can now save on your purchases or even make a purchase by simply tweeting special hashtags. Here is how it works:
First you sync your Amex online account with your personal Twitter account at sync.americanexpress.com/twitter. Then stay connected to the American Express twitter feed to be updated with the latest available offers. If you are interested in an offer simply publish a tweet using the offer’s hashtag (i.e. #AmexFlowerOffer) and the discount will automatically take place once you pay using your card.
Amex even push it further by allowing you to place a purchase directly with a tweet following the same hashtag concept (i.e. #BuyDigitalCamera). The item you purchased will be directly shipped to your address once you send a purchase confirmation tweet (#ConfirmDigitalCamera).
In terms of security and privacy which is a primary concern when it comes to social media in the banking and finance industry, let’s hope American Express has a well established procedure for hacked twitter accounts.
