"Focus on the experience of every input" is ES Dongcheng's product attitude towards silicone buttons.

The use demands of visually impaired and elderly users also need to be met.

The development of intelligence and thinning of electronic products is particularly evident in POS equipment in the financial payment industry.

In recent years, the touch-screen password input of POS machines has gradually replaced the input method of the traditional physical key panel.

In shopping malls, airports, hotels, unattended and other payment scenarios, there are some visually impaired or elderly users. The smooth and floodlit touch screen of the smart POS machine prevents them from accurately finding the number they want to enter. , and it cannot give them the sense of security of the feedback force brought by the resilience of the physical buttons. The intelligence of POS machines has brought a bad experience to these users.

After discussion and research, our product manager developed and designed a smart POS machine with external blind buttons for the needs of visually impaired and elderly users:

The whole structure of this external blind button is made of silicone, which is soft, comfortable and environmentally friendly;

The shape and function can fully achieve the same effect as the traditional physical buttons of POS machines;

The overall structure and shape can be customized according to the size of the smart POS machine, and the inner side of the button is polished to prevent it from falling off and closely fit the touch screen of the smart POS machine;

· When pressed, the bioelectricity of the human body is conducted to the corresponding contact points of the touch screen through the conductive silica gel in the middle, so as to perform input operations.

In the early stage of the development of blind buttons, the biggest problem was that the conductive silicone and the insulating silicone were not firmly bonded, and were easy to fall off, affecting the service life.

ES Dongcheng developers repeatedly verified and debugged, and finally overcome all difficulties perfectly by modifying the structure of the product and introducing intermediate PC chips;

Successfully developed external physical buttons suitable for smart POS machines for visually impaired and elderly users to ensure that such people can meet the needs of smart POS machines.

This POS machine has external buttons for the blind. At present, ES Dongcheng has obtained the national utility model patent, patent number: CN201920983885.X
