Mobile payment is the process of using a smartphone or other mobile device to pay for goods or services, either online or in-person, without the need for cash or cards. It is becoming increasingly popular among consumers, especially millennials and Gen Z, who value convenience, speed, and security. According to a report by Juniper Research, mobile payment transactions are expected to reach $3.7 trillion by 2024, up from $1.8 trillion in 2019. For hotels, mobile payment can offer several advantages such as reducing friction and increasing revenue and loyalty by enabling guests to make impulse purchases or join loyalty programs with a few taps on their phones. Furthermore, it can improve operational efficiency and cost savings by reducing the need for staff, hardware, and paper receipts while streamlining the payment process. Additionally, it can enhance security and compliance by using encryption, tokenization, and biometric authentication to protect guest data and prevent fraud.
