Members of Nectar will be able to locate businesses participating in the scheme via the Nectar website, by clicking on the "Find Rewards in your area" link. This will tell them were they can find outlets such as Argos, Blockbusters, Cannons health clubs and Cafe Uno, where they can earn more points or redeem points they have already earned.
Jeff Kelisky, Multimap's chief executive officer, said: "The mapping and local information services that we provide to our customers offer a significant enhancement to the end-user's experience online."
The deal has been done to boost the online experience for users and to improve frequency of use of the site and, ultimately, the loyalty programme.
Simon Hawkes, chief operating officer at Loyalty Management UK, said: "Multimap's flexible technology, which was deployed quickly and smoothly, means that Nectar Collectors are now able to find their nearest Rewards suppliers and sponsors in a matter of seconds.
"This is great for collectors, and great for our rewards partners, who see traffic through the doors increase considerably."
Multimap is one of the 10-most visited websites in the UK, with 90m page impressions a month.
