What they have in common is their crucial role in a vast array of applications. From tracking inventory to managing logistics in the supply chain, patient safety in healthcare, and security through fingerprint or other biometric verification, AIDC technologies can virtually eliminate errors, boost productivity, and provide a wealth of real-time data that can be leveraged to make more informed decisions.

AIDC technologies are about more than just operational efficiency – they are about transforming businesses and the way people experience the world. By automating the identification and data capture of virtually any asset in any industry, organisations can work smarter – from improving their operations and customer experiences to ensuring the authenticity of their products. Increasingly, as we look ahead to the next chapter of digital transformation, we are seeing the impact of these technologies isn't just in innovation – they're driving it. AIDC technologies are critical in enabling everything from smart cities and buildings to the Internet of Things (IoT).


What is AIDC?

Automatic identification and data capturing is a technique that identifies objects, collects data about the identified objects, and enters a computer system directly without human involvement. It allows a user to scan an item that is barcoded. Information about an object is called identification data. This data may be in images, sounds, or videos. This data is converted before it is fed into the computer system. A transducer converts the actual data into a digital file. This file is then fed into a computer system. The data file may be stored in the computer's memory or in a separate file storage device. A computer examines the stored data file and compares the file with other files in a database to verify that the user has been authorised to enter a security system.
