<p>A user's smart phone is used for payments and holding information, similar to what is contained in a physical wallet. Depending on transaction details, user preferences, and location, one or more “best” funding instruments for the transaction are selected for the user, who may then revise if desired. Access to different functions or information within the phone may vary and require different authentication/security levels depending on type of use (e.g., payment or non-payment) and details of use (e.g., high payment amount vs. low payment amount, use of sensitive information vs. non-sensitive information).</p> |
