Concept
Smart label
Summary
Smart Label, also called Smart Tag, is an extremely flat configured transponder under a conventional print-coded label, which includes chip, antenna and bonding wires as a so-called inlay. The labels, made of paper, fabric or plastics, are prepared as a paper roll with the inlays laminated between the rolled carrier and the label media for use in specially-designed printer units.
In many processes in logistics and transportation, the barcode, or the 2D-barcode, is well established as the key means for identification in short distance. Whereas the automation of such optical coding is limited in appropriate distance for reading success and usually requires manual operation for finding the code or scanner gates that scan all the surface of a coded object, the RFID-inlay allows for better tolerance in fully automated reading from a certain specified distance. However, the mechanical vulnerability of the RFID-inlay is higher than the ordinary label, which has its weaknesses in its resistance to scratch.
Thus, the smartness of the smart label is earned in compensation of typical weaknesses with the combination of the technologies of plain text, optical character recognition and radio code.
The processing of these labels is basically as with ordinary labels in all stages of production and application, except the inlay is inserted in an automated processing step to ensure identical positioning for each label and careful processing to prevent any damage to the bonding.
The printing is processed in two steps, including
normal ink-jet printing, except the space with the bonded chip, with clearly intelligible text and
either barcode or 2D barcode for later semi-automatic reading with handheld readers or fix-mount scanners
writing coherently concatenated information to the RFID-chip
reading the written information on the RFID-chip subsequently in the printer for control purpose (read after write)
Customisation of smart labels is available with chip cards. Also combinations of magnetic stripes with RFID chips are used, especially for credit cards.
