Not so sure how we feel about this, but give us a month. From USA Today:
Credit card company American Express has announced a partnership with Twitter that allows cardholders to purchase items by simply typing in a hashtag. American Express members can visit the company’s website to sync their accounts to Twitter.
Here’s how it works: when a user sees an item they want to purchase, they type a special hashtag. For example, American Express is offering a $25 gift card for $15 users can snag by posting the hashtag #BuyAmexGiftCard25. Twitter users then check the Mentions tab for replies from @AmexSync that include a confirmation hashtag. Users have 15 minutes to tweet the confirmation, then their item will be shipped to the billing address tied to their credit card.
So now not only will everyone know you have an AMEX card, you will also be getting publicity for the product you’re buying. Which one of you online shoppes can’t wait to try this?
