The mystery ended yesterday afternoon as J.P. Morgan Chase delivered official notification to TSYS to continue providing processing for the combined Chase and Bank One card portfolio for now. Exclusive negotiations are currently underway for a definitive contract, that Chase says it expects to sign within a few weeks. Under terms of yesterday’s deal, TSYS will also complete a planned upgrade of card-processing technology under a previous contract with Bank One. In the future, Chase will have the option to transfer card processing services in-house under a license of the “TS2” software. The combined Bank One and Chase portfolio has approximately $125.2 billion in outstandings, based on first quarter results. The portfolio has about 87.2 million cardholders, and 71.8 million accounts, according to CardData ([www.carddata.com]).
