45 Years Experience

45 years of core radio frequency technology and product manufacturing capability.

Since the beginning of our business as Samsung Electro-Mechanics in 1973, we have been expanding our business area. From existing business such as TV Tuner, Wireless communication modules (BT, GPS, WLAN), TV/Mobile power modules, and IoT modules & products, SoluM’s Core IC design capability made it possible to start our ESL business in 2007 with our own manufacturing facilities.

Over the past five years, we have grown fast and have now installed more than 50 million ESLs in over 30 countries and over 4,000 stores worldwide. We have gained a good reputation in the ESL markets (grocery, department stores, electronics, factory, warehouse and apparel store) through stable server and management software, diverse and differentiated product lineup, and prompt and active customer service.
