How to treat uncle's practice of making a three-layer insurance wallet with iron locks? Is it really necessary?

When a 60-year-old uncle bought oranges at a fruit stand, the stall owner found the wallet around his waist very interesting. Looking carefully, he found that the wallet used by the uncle was a three-layer insurance wallet made of iron locks, and many keys were hung around the wallet. When uncle opened these locks to withdraw money, the stall owner also helped him find the key to unlock it. When uncle opened the three-layer insurance wallet, there was not much money inside. However, the uncle's awareness of prevention is really strong, and he should be afraid of losing money, so he designed a three-layer insurance wallet. Many netizens said that it is rare to see an uncle keep his money like this.

Although uncle's three-layer insurance wallet looks safe, if it is lost, people will open it easily. Not only that, this three-layer wallet is particularly conspicuous after hanging on the waist, and it is easy to be targeted by people with a heart. Moreover, there is not much money in uncle's wallet, so just take an ordinary wallet with money, and you don't need to spend too much energy to make such a clumsy wallet. Not only do you need to find the key when you open it.

Maybe my uncle lives in the countryside and attaches great importance to money, so he puts the change in the three-tier insurance wallet. As a person who pays by mobile phone every day, it is understandable. If they learned to pay by mobile phone, they wouldn't need to design such a clumsy wallet. I also hope that my uncle can learn to pay with payment software such as mobile phone as soon as possible in the future, which can not only protect his own funds, but also avoid the risk of receiving counterfeit money. Secondly, it will also protect his own money.
