Most counterfeit cards now are achieved by rewriting the magnetic strip on the invalid card, so the method of going to an ATM or POS mentioned in answer 1 is incorrect. The identification of cards by these machines is limited to reading the card's magnetic stripe data. Now regarding how to identify the authenticity, I will borrow the answers from other netizens:

Methods for identifying the authenticity of international Visa cards. Recently, the Jinjiang Municipal People’s Court proposed the method for identifying the authenticity of international Visa cards. Pay attention to the following four points:

1. All genuine Visas have an internationally unified security design. Member banks and approved manufacturers must abide by the regulations. Common counterfeit credit cards on the market have security designs on their cards that are consistent with The real cards don’t match.

2. The bank identification number (i.e. the first six digits of the Visa card account number) represents the ID number of the Visa issuing bank. The bank name printed on the fake card usually does not match the bank identification number.

3. The (Flying Pigeon) hologram attached to the real Visa is three-dimensional and manufactured by two recognized manufacturers in the United States and the United Kingdom. Common fake credit cards on the market have the (Flying Pigeon) hologram attached to them. , generally two-sided and three-dimensional, inconsistent with the real card.

4. Surrounded by the Visa blue, white, and gold logo is a micro-printing, which prints the first four account numbers on the card, the card type and the approved manufacturer code. Common fake credit cards on the market, large Most are not microprinted.

The legal provisions regarding credit card fraud are:

(1) Using forged credit cards, or using credit cards fraudulently obtained with false identification;

(2) Using an expired credit card;

(3) Pretending to use another person’s credit card;

(4) Malicious overdraft.
