Introducing LinkRay Technology

Using visible light communication, LinkRay delivers mobile content by enabling ordinary smartphones* to read IDs sent from LED transmitters, such as displays, signboards, and spotlights, and to connect to associated mobile content. LinkRay delivers impactful end user experiences intuitively, easily, and securely.

Potential capabilities include:

  • Launching mapping applications or transport timetables for tourists
  • Reporting traffic conditions in real time
  • Offering coupons and product information in retail environments
  • Accessing apps designed to enhance the experience at cultural institutions

Instantaneous, accessible from a distance, and resistant to interference, LinkRay also provides invaluable marketing analysis tools for targeted advertising aimed at opt-in users, and can help optimize environments for increased sales and service.

Answers to Frequently Asked Questions

What do you need to read LinkRay?

A smartphone whose operation has been confirmed, a smartphone application (LinkRay Service Provider App) created by a LinkRay Service provider, and a "LinkRay" App are required.

The first time you read a LinkRay with a LinkRay Service Provider App, a message will appear asking you to install the "LinkRay" App.

The "LinkRay" App is used in common for receiving LinkRay information, and once it is installed in the smartphone, it can be used for all LinkRay Service Provider Apps.
