One of the main tasks was to solve the problem of the eternal lost of cash and bank cards. With this in mind our solutions were based off the fact that through multiple testing and interviewing we established that most customers had smart phones that either had facial recognition and most of all they had fingureprint scanning as a sense of security on their mobile devices and we decided to leverage on thet already exisiting feature to create a second authentication before a purchase is done by a user.
This allowed us, through various tests to come to the conclusion that fingurepint security would be the best way to solve.
