- Disclosed herein are a method for recognizing a table for an electronic menu system based on visible light and an apparatus for the same. The method includes receiving, by a visible light receiver connected to a smart device provided to a customer in a restaurant, multiple visible light signals from multiple lamps installed in the restaurant; detecting at least one valid signal from the multiple visible light signals in consideration of the multiple visible light signals and sensor data collected from a sensor installed in the smart device; and recognizing a table at which the customer is sitting using table information included in the at least one valid signal.
