Google and Apple are just two of the many players in the increasingly crowded field of mobile payments. The two companies have a huge set of resources and funds to figure out what will attract consumers, make acquisitions, and form partnerships with retailers and banks.
The problem with mobile payments is that there isn't exactly a problem to be solved. Credit cards and cash work just fine. So Apple and Google are left trying to figure out why a consumer would use a mobile wallet instead. Both companies seem to be betting heavily on loyalty as the answer.
Apple Pay is already accepted at hundreds of thousands of stores, including retailers such as Macy's (M) and Toys R' Us. Though Apple does not share current numbers on how many consumers use the service, CEO Tim Cook said earlier this year that more than 1 million consumers activated a credit and debit card on Apple Pay during the first 72 hours after it was released.
At its developer conference on Thursday, Google announced a new platform called Android Pay, which essentially acts like Apple Pay but for Android phones. Android Pay -- which Google's Sundar Pichai, senior vice president of Chrome, Android and apps, briefly discussed at Mobile World Congress in March -- will allow consumers to connect their credit cards so that they can pay for purchases with apps and in physical stores. Android Pay will use fingerprints to authorize transactions and will work at any store that has an NFC terminal (the same technology used with Apple Pay).
