American Express (Amex) has launched a purchase-by-tweet service for its US-based customers.

Credit-card holders post a specific hashtag on Twitter to trigger payments from their accounts.

Products from Amazon, Sony and Microsoft are being offered at a discount to entice shoppers to use the new service.

However, one retail expert dismissed the initiative as a “gimmick” that was unlikely to catch on.

This is not Amex’s first tie-up with social media.
