Press release	At the 2013 Hanover Trade Fair, IPH presents a new all-in-one-label combining the advantages of matrix codes, labels, and RFID

Automatic identification systems are used to mark and identify objects in industry and everyday life. Today various automatic identification systems co-exist. The most important are matrix codes (e.g. EAN barcodes, QR codes), labels, and RFID tags. Each of these systems has its advantages and disadvantages. Barcodes can be decoded by machines, but not read by humans. Once saved, information cannot be modified. Printed labels can be interpreted by humans. But they are neither readable by machines nor rewriteable. RFID tags are the sole ID system that combines the abilities of being rewriteable and readable by machines. Humans, however, cannot decode the information without a reader with a display. So far, matrix codes, labels, and RFID tags are used alongside each other. Yet they are hardly compatible. Combinations of individual ID systems like RFID and labels do already exist. However, when information stored on either one is changed, the information saved on the other information carrier no longer matches. In a two-year research project, IPH engineers have developed an automatic identification system based on visible light. The new all-in-one label combines the advantages of existing ID systems: It is rewritable like an RFID tag and interpretable by both machines and humans.

ID-methods like RFID or barcodes are used for fast digital data access. Unfortunately the informaton is not readable by humans without a special device, which can cause several logistic problems. Therefor a new Auto-ID label was designed in the research project "IdentOverLight", that is readable by humans and transmits data wireless using visible light communication.

In the research project "IdentOverLight" a new Auto-ID system ,using visible light communication, was developed. The new label combines the advatages of existing Auto-ID systems. It is rewriteable like RFID, machine-readable like Barcodes and readable by human like labels.

The approach "Ident Over-Light" combines the positive features of existing auto-ID methods such as RFID, barcode and labels, in a new concept, whose special feature is the visible light which is used for communication with the information carrier. The information carrier is rewritable and automatically readable both for the employee in plain text as well as for an automated reading system.

Logistics is an essential part of the value chain. Therefore, sustainable logistics systems are a decisive competitive and success factor for companies. Through individual customer requirements, shorter innovation cycles and an increasing variety of product types, the requirements have become increasingly complex in the material handling engineering sectors. To meet these requirements and to allow a continuous increase in efficiency of logistics systems, the development of innovative systems is necessary. A key to the design of such systems is the use of optical technologies. Using a simplified scenario the possibilities of optical technologies in intralogistics are represented in this paper.
