2. Look at the plastic film. The real card has a smooth surface and the card material is more elastic. Under the ultraviolet light, the bank logo or the name of the card issuer will appear on the card, which is the laser anti-counterfeiting label. The surface of fake cards is rough, the color is easy to fall off, and the negatives generally have no anti-counterfeiting design.
