Mobile payments expert witness candidates typically have extensive experience in banking, information security, and/or computer science.

A mobile payment is a payment service transacted via a mobile device. There are multiple ways to transact electronic payments, with more secure and convenient methods being developed. Mobile banking can be as straightforward as paying via a browser with a credit/debit card. A mobile payment can be transacted “contactless” or in person. Most contactless card machines use near-field communication (NFC) payments technology, where a mobile phone doesn’t have to physically touch a point of sale to transfer information, but has to be close to the terminal. Another trending mobile payment method is a “mobile wallet” that stores payment information on a mobile device (usually in an app). While many mobile wallets use NFC, other technologies such as “quick response” (QR) codes can be utilized. QR codes work through banking apps associated with credit/debit cards. This method is more secure because your phone actually confirms the owner of the card. Unfortunately, electronic payments hackers continue to find ways around technology security, and there is ongoing development in the area of information security.
