I’m currently traveling around the village doing research. From Hokkaido in the north to Okinawa in the south, we have picked up unique villages and observed their regional revitalization efforts centered on digitalization. The main means of transportation to get there are trains and rental cars. Since it’s my job, I want to proceed in a timely manner. That’s why I book everything in advance. Since it is troublesome to make reservations at the counter or over the phone, I make online reservations and pay by credit card. You can make reservations and payments anytime and anywhere, saving you time and convenience.

Recently, however, there has been an increase in the number of cases in which online reservations cannot be made due to poor credit card payments. In such a case, call your credit card company and explain the situation. In most cases, the card has a security lock that prevents it from being used, and you will need to have the lock unlocked. Once the lock is released, you can use it normally. Online reservations are convenient, but when problems occur, they quickly become troublesome and difficult to use. It’s painful and itchy.
I was having problems with card payments so frequently that I contacted my credit card company. If there’s a problem with how I use it, I’ll fix it, but if not, I’d like to know the reason for the problem.

According to the card company, the decision on whether to apply a security lock is made by AI. In particular, the use of internet services is subject to strict judgment. People are being especially cautious about transportation-related online services that I often use. This is because the service has become a hotbed for online crime and fraud.
”I see.However, I will be using that service quite a bit for a while on business trips, etc.It would be a problem if it locked up frequently,” I said.
”We apologize for the inconvenience, but there is a security issue.If you contact us, we will unlock the lock immediately,” the credit card company said.
Considering the recent situation where cyber-attacks are intensifying, I can’t help but agree. (Kei Kitajima)
