Mobile payment services allow users to make financial transactions using their smartphones or other mobile devices. These services enable users to pay for goods and services, transfer money, and manage their finances without needing cash or physical credit cards. Popular examples include Apple Pay, Google Pay, and PayPal. These services typically use technologies like Near Field Communication (NFC) or QR codes to facilitate secure payments. Users can link their bank accounts or credit cards to these apps, making transactions quick and convenient. Mobile payment services are increasingly popular due to their ease of use and the growing trend towards digital wallets.
