first, look at the plastic film. The real card has a smooth surface, the color is not easy to fall off, and the negative has anti-counterfeiting marks; The surface of fake cards is rough, the color is easy to fall off, and the negative film is generally without security design.
the second is to look at printing. Real cards have bright colors and clear words, and the stripes on the card surface are inspected neatly; The words of the fake card are vague, the color is too dark or too light, and the stripes on the card surface are irregular, just like sticking it on a white card.
third, look at the signature column. The real card has the trademark of the duplicate card issuing company; The fake card has no company trademark, that is, it is all white or has traces of alteration, and the signature is not smooth.
fourth, look at embossing. Real Kaka number capitalized English letters are neat and orderly; The stamped number of the fake card is irregular or different in size from the English letters, and the old card number of the altered card is faintly visible on the card surface.
if you master these items, you can basically tell the true and false credit cards.
