RFID (Radio Frequency Identification) allows the contactless, automatic identification and localization of objects without line-of-sight contact.

RFID is considered to be a key technology for increasing the efficiency of global supply chains and is increasingly used in industry and logistics.

A read/write device communicates with the RFID tag using low range radio signals. The data which is stored in the RFID tag can be read, overwritten and added to. This is not possible when using simple barcodes.

The RFID system consists of the following components:
– RFID tag (for example a special label which contains an RFID chip)
– RFID detector or read/write device
– Application software

  Compared to other auto-ID technologies, RFID has the advantage that the data is read without an electrical connection and without line-of-sight contact. In addition, the RFID system is resistant to humidity, oil, dirt and abrasion.

Altec supplies special RFID solutions with additional encryption algorithms which provide extra protection against fraud and unauthorised modification of the data.

During a manufacturing process, RFID allows up-to date information to be read from the RFID tag which is attached to the component or container/palette. As the component passes through the assembly line and is merged with other components to form the finished product, the read/write device can update the part name and part number in the RFID tag. This is a decisive advantage when compared to labels, barcodes or accompanying documents.

By providing the read/write device with software interfaces to production and/or inventory control systems, RFID technology can allow a paperless manufacturing process.
