[0005] Preferably, a white dot is provided at one end of the outer side of the black acid vinegar cloth. By marking the white dot on the fingerprint recognition line, the functions of different electrical signals can be accurately identified and distinguished, avoiding malfunction or damage of the device caused by incorrect connection.

[0006] Preferably, the width of the black acid vinegar cloth is set to ten millimeters, and the lay length of the wound wire is greater than or equal to twelve millimeters.

[0007] Preferably, the outer diameter of the middle of the black acid vinegar cloth is set to 2.2±0.3. By setting the width, twist length and outer diameter of the black acid vinegar cloth after winding, the fingerprint recognition line after wrapping can easily twist a single core without spreading.

[0008] Compared with the prior art, the utility model provides a high-precision fingerprint recognition line, which has the following beneficial effects:

[0009] 1. The high-precision fingerprint recognition line, by setting the width, twisting distance and outer diameter of the black acid vinegar cloth after winding, can make the fingerprint recognition line after wrapping easily twist a single wire core without spreading out. The black acid vinegar cloth has the characteristics of high temperature resistance, aging resistance, softness and fit, good shape, easy punching and unwinding, acid and alkali resistance and mildew resistance. The insulation performance is better than that of general glass fiber cloth and glass cloth, which improves the safety and service life of the fingerprint recognition line.
