The world's biggest retailer, Wal-Mart Inc, is to launch a credit card for its Wal-Mart stores chain that can be used on Morgan Stanley's Discover network.

GE Consumer Finance, which is part of General Electric, will issue the card in March.

The card is for use both inside and outside of Wal-Mart stores and will not have an annual charge.

Wal-Mart Stores Inc predicts that January 2005 sales for its US division will rise by between 2 per cent and 4 per cent compared to January 2004 results.
