First Data Resources Ltd., the European processing affiliate of First Data Corp., said it has completed its largest customer conversion, moving 4.7 million cardholder accounts from an in- house system of the former Trustee Savings Banks.

The TSB portfolio, now part of Lloyds TSB, a longtime customer of the First Data unit, brings the processor's business up to 22 million accounts.

Joe Jackson, managing director of FDR Europe, said the conversion occurred "on schedule and in line with the expectations of our client," which was counting on "systems reliability and flexibility" to justify its consolidation decision.

First Data "handled Lloyds Bank processing for many years, and it was logical for us to move our combined portfolio to one platform," said Gerald Hawkins, Lloyds managing director, card services.
