Application

Medical Industry
Suitable for installation in hospitals, doctor's offices and clinics, the user-friendly
intuitive touch interface promotes faster and more accurate medical data input and
retrieval. It can increase administrative efficiency, and improve the delivery of health
care.

Transportation
From train stations to airports, touch screen interface devices are used in almost all
forms of mass transportation. Its applications can decrease training time, increase
productivity, create higher quality products and service, and raise profits.

Gaming
From casinos and entertainment centers to countertop and bar environments.
Touch screen interface devices have been used to provide an easy and fun way to
interact. Easy to integrate touch software has expanded the potential for creating
exciting new games.

POS
For point-of-sale OEMs, resellers, distributors, and end-customers, we have the right
touch. The easy-to-use touch screen enables POS distributors to provide products that
help customers reduce employee training time and speed-up transaction.

Office Equipment / Industrial PC
From process automation and quality control to employee training and communication,
ELO is the choice of the leading developers of industrial automation software. The
compatibility of our touch screen drivers with different software applications provides
them with the flexibility they required to improve their management efficiency.

Kiosks and the Public Access Applications
From trade show booths to retail outlets and from public environments to Web phones,
touch screen with our built-in Kiosk system provides interactive multimedia solutions.
They enable Kiosks to be used in environments where a keyboard or mouse is not
practical.
