Counterfeit watermarks are printed with colorless ink on the front side of the paper, and the watermarks are blurred and have no three-dimensionality.

The second look at the security line. There is a window security line on the back of the real coin, and the holographic pattern consisting of the miniature character "500" can be seen in the open window part; the fake coin is sandwiched between silver and black magnetic tape in the front and back of the paper, and stamped with silver ink on the back or printed with black ink in the front of the black stripes, and stamped with silver ink on the back of the holographic pattern, and brushed with magnetic powder.

Four look at the invisible denomination figures. Counterfeit invisible denomination figures, printed with colorless ink, without the need to rotate the angle to see the word 50.　　

Five look at the ticket pattern is clear, color is bright. Yin and Yang is complementary to the printed pattern of misplaced banknotes are certainly counterfeit.

Touch: touch the portrait, touch the blind spot, hand-carved avatar, the People's Bank of China name, intaglio printing feel line, etc. Whether there is a sense of concavity, there is no sense of concavity of the counterfeit currency.

Listen: we can shake the banknote to make it sound, according to the sound to distinguish between the real and fake RMB, the real banknote paper has a straight, folding, not easy to tear the characteristics; holding the banknote shaking hard, finger flick or two hands of one hand symmetrically pulling, you can hear the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound of the sound. The fake paper is soft, no toughness, and the sound is dull when shaking hard.
