A mobile wallet is a digital or electronic wallet that allows users to store and manage their payment information on their smartphones. This includes credit/debit card details, loyalty cards, gift cards, etc., which can be used for making payments at the point of sale (POS) using NFC (Near Field Communication) technology or QR codes. The mobile wallet provides a convenient and secure way to make transactions without having to carry physical cards with you. It is also often integrated with other features such as mobile banking, digital receipts, and rewards programs.
