Mobile payment system refers to a business system that can perform e-commerce operations such as consumption, recharging, transfers and remittances, and inquiries on mobile phones with the support of mobile communication networks and Internet technology. In fact, I have always paid by credit card in Rome before, so I didn’t use mobile payment.

There is actually a reason why my country has launched mobile payment. First of all, our country has a large number of customers who own mobile phones. Because there is such a large and stable customer base, this provides a foundation for the development of mobile payment business. When mobile phones become a part of people's lives, mobile payment services will also be accepted by more mobile phone users. Coupled with the increasingly mature mobile Internet access technology, mobile phones have transformed from simple communication tools into carriers with multiple functions. Mobile phones can not only make calls and send text messages, but also have many functions such as surfing the Internet, buying tickets, and booking hotels. With the development of information technology, mobile phones will become a daily utensil with increasingly complete functions.

At present, the popularity of mobile payment systems in Western countries is not that high. This is actually due to the widespread popularity of credit cards in Western countries. When Western consumers choose between "credit card payment" and "mobile phone payment", after all, they tend not to immediately change the "non-cash payment" they have been accustomed to for many years, or they will "prioritize" credit card payment and "mobile phone payment". "Payment", so this makes many merchants dare not completely give up "credit card payment" and give up POS machines immediately. Therefore, the proportion of "mobile payment" in "non-cash payment" is not high in the West and is lower than that in China.

To sum up, we can understand why Rome is only now using non-paper currency for payment.
