PARIS (AP) - Did someone spot you some money for lunch two weeks ago? In France, Twitter users can now publicly repay debts, donate to charity or chip in for a gift with a new payment service backed by the country's second-largest banking service.

PARIS (AP) Did someone spot you some money for lunch two weeks ago? In France, Twitter users can now publicly repay debts, donate to charity or chip in for a gift with a new payment service backed by the country's second-largest banking service.

Group BPCE, which includes Banque Populaire and Caisses d'Epargne, announced the service called S-money on Tuesday.

Users tweet a payment request to S-money, which then requires an authentication code before sending the amount and a tweet to the destination confirming payment for all the world to see.

Armand Dos Santos, chief technical officer for S-money said: "We think that this is quite interesting for the Twitter user to be able to communicate the financial transactions that he has made."

The service only works between French users.
