AI Technical Summary
In existing technologies, the vertical stacking design of the NFC coil and circuit board leads to signal attenuation, affecting the wireless communication effect.
The NFC coil is mounted on the bottom of the housing, and the printing module is located above it. The circuit board and the printing module are arranged side by side in the horizontal direction to form a barrier, avoiding vertical stacking and shortening the signal path.
It improves wireless communication performance, ensures the signal strength of the NFC coil, and enhances wireless communication between devices.
