Lee, who lives in Gwangju, was introduced to his acquaintance in February last year by an acquaintance.

If you pay someone else's tax with your credit card, you can receive a 2% commission as well as the principal.

I was uncertain, but I was reassured that the payment of local tax cards was legal and the lawyers were involved.

As a test, he handed a card, and the principal and fee were actually deposited monthly.

Mr. Lee eventually handed his cards to his family and relatives.

But half a year later, in September of last year, there were no charges or credit cards.

Such tens of millions of won and hundreds of millions of won of the card was indebted to the victims.

In total, 550 people suffered damages of 26 billion won, and they fell into bad credit or disbanded their families.

Most of the victims were middle class and common people.

There is also a loophole in the credit card company's 'fault detection system' (FDS), which detects abnormal transactions.

He also testified that at least hundreds of attorneys handed over tax bills to the fraud squad through brokers.

As well as Gwangju, Daegu suffered 10 billion won in fraud, while similar fraud cases were in progress in other areas, including Mokpo.

The New Story explored the substance of the new card fraud case, which was based on the legal payment of local taxes, and the problems of card companies and some lawyers.
