Why it’s good to have two or more credit cards

I think it’s better to have two cards from different credit card companies and international brands. Also, the benefits of debit cards are as follows, but I think you need to think about how you use them.

・It is easy to notice fraudulent use because the money is immediately deducted from your account.
・You can control suspension and resumption of use by yourself
・Even if a crime occurs, no amount exceeding the amount deposited into the account will be stolen.

When making large payments such as airline tickets, the payment may not be completed at the critical moment.

Reason

Security requirements vary by credit card company and international brands.
In my case, when I purchased a flight ticket for CHINA AIRLINES (Taiwan), I was unable to purchase it because credit card company of VISA was used for confirmation.

Skimming measures

It seems effective to carry two international brands to prevent skimming.

Reason

I heard that skimming is about the size of a cigarette pack, but it has the characteristic of scanning one page at a time, and it seems that it cannot read two different pages of electronic information at the same time.

Anti-theft measures

If you only have one, and in the worst case scenario it gets stolen, you won’t be able to continue your journey.
To prevent theft, it is safer to store the two cards in separate locations.

how to deal

Even if you run out of one, you can continue your journey because you have it. This measure is effective for everything. cash, electronic devices, etc.
