Mobile payment systems allow users to make transactions using their smartphones or other mobile devices. These systems enable payments for goods and services through apps or digital wallets, such as Apple Pay, Google Pay, or Samsung Pay. Users can link their bank accounts or credit cards to these apps, making it convenient to pay without cash or physical cards. These systems often use technologies like Near Field Communication (NFC) or QR codes to facilitate secure transactions. Mobile payment systems are becoming increasingly popular due to their speed, ease of use, and enhanced security features, making shopping more efficient for consumers.
