The deal could also provide invaluable information about customer behavior, Jupiter Research's Julie Ask said.
"It gives both McDonald's and DoCoMo the opportunity to track consumers and their eating habits. Cash is more likely to be used in small transactions. Electronic payments will allow user behaviour to be tracked and used for marketing purposes," Ask said in her blog.
McDonald's is just another retailer that is offering mobile phone payment in Japan. DoCoMo has set up service which allows around 3 million customers to use their handsets as credit cards.
