POS Machine Braille Buttons for Visually Impaired & Elderly Users

Product Overview

As touchscreen interfaces have largely replaced traditional physical keypads in modern POS equipment, visually impaired and elderly users—who rely on tactile feedback for number entry—face significant challenges during payment transactions. The smooth, backlit screens of smart POS terminals provide no positional reference or tactile confirmation, making independent operation difficult. This external braille keypad was developed specifically to solve that accessibility problem.

The button is crafted from soft, comfortable silicone with a polished inner surface that secures tightly against the touchscreen without detaching. When pressed, the black conductive silicone center—formed via a secondary overmolding process—transfers the user's bioelectricity to the corresponding screen contact points for accurate input. Its travel distance and structural design are carefully engineered to replicate the familiar feel of traditional physical POS buttons, delivering the tactile confirmation that glass surfaces cannot provide. During development, ES Silicone successfully resolved bonding failures between conductive and insulating silicone layers through structural optimization and intermediate PC chip integration—a breakthrough that earned the National Utility Model Patent (CN201920983885.X).

Core Advantages

1. Conductive Silicone Technology with Secondary Overmolding : The black conductive silicone section is formed via a secondary overmolding process, precisely integrated with the insulating silicone body. When pressed, it transfers the user's bioelectricity to the touchscreen contact points, enabling accurate input without modifying the POS terminal itself.

2. Soft, Comfortable Silicone Construction with Familiar Tactile Feel : Made entirely from soft, comfortable, environmentally friendly silicone, the keypad provides the familiar tactile feedback of traditional physical buttons—giving users the sense of security and confirmation that touchscreens cannot offer.

3.Patented Design Overcoming Conductive/Insulating Silicone Bonding Challenges : ES Silicone developed innovative structural solutions and introduced intermediate PC chips to solve the bonding failure issues between conductive and insulating silicone layers, achieving reliable durability and securing a National Utility Model Patent (CN201920983885.X).
