Argos and Homebase have implemented the Intelligent Environments NetFinance platform in order to improve their tailoring of offers to card holding customers.
Home Retail Group Financial Services, the financial arm of the Argos and Homebase brands, will be the first of the two to adopt the module.
The tool is aimed at providing financial and retail offers to Argos and Homebase store card holders via their online accounts. Intelligent Environments already provides customer online card services facilities to Home Retail Group Financial Services, which customers access.
Under the "My Extras" feature online customers will be sent personalised messages and offers in response to their retail activity. Customers can print off vouchers and redeem them in stores.
Katie Wilson, head of marketing at Home Retail Group Financial Services, said: "By adding this module onto our platform we can maximise the usage of the online channel and make sure our customers are aware of all special offers and vouchers that are available to them."
Online and mobile app-based sales at Argos, alongside orders through customers' TVs, made up almost half of its total revenue last year.
