The Self-service POS machine is a self-service terminal device for customers ordering food. It replaces the traditional cashier, reduces the queue waiting, improves the restaurant level, and realizes the no-contact ordering. Ordering software will be released soon. It has the following characteristics:

The touch screen is an important source of input and output devices, usually layered on top of the electronic visual display of the information processing system.

Water will increase the capacitance, which will affect the capacitive touch screen to judge the signal, easy to lead to touch response speed drop, drift, ghost spots, in most cases, it is difficult to recover the original touch sensitivity.

Touch film is a transparent film that can accurately perceive the touch of human hand across the substrate (referring to non-metallic substrate, including glass, acrylic, wood, plastic, etc.). It is the core component of the precise positioning device such as the touch screen, which mainly solves the problem of accurate touch positioning.

The process of anti-reflective glass is mainly achieved by coating a thin film on the surface of the glass, which can effectively prevent reflected light and thus improve the transmittance of the glass.

The use of capacitive touch screens in access control systems is becoming increasingly popular due to their ease of use and reliability. Capacitive touch screens are a type of touch screen technology that uses electrical current to detect the presence of a finger or other conductive object. This technology is used in a variety of applications, including access control systems.

Capacitive touch screens are becoming increasingly popular in medical products because of their ability to provide a more accurate and reliable user experience.

Capacitive touch screens are often used in combination with USB interfaces and I2C interfaces to provide a more powerful and reliable user experience.
