Fair, Isaac & Co. said it has sold its Customer  Management Triad adaptive control software to Halifax Group PLC of the   United Kingdom.   
The companies said the installation is expected to increase sales,  reduce costs, and improve service in the banking and consumer credit   division, which includes transaction account, credit card, and personal   loan operations.     
  
As part of a relationship banking strategy, Halifax aims to "give  customers with multiple products full value for their loyalty," said Peter   Taylor, head of banking credit operations. "We hope to increase sales as a   result of improved assessment of our total exposure and risk appetite to   any particular customer at the point of sale."       
Halifax also bought risk and attrition behavior-scoring models to aid  in collections, credit-limit allocations, and marketing to existing   customers, as well as in the booking of mortgages.
