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,

Types Of Smart Labels

Chip Labels

Customisation of smart labels is available with chip cards. Also combinations of magnetic stripes with RFID chips are used, especially for credit cards.

Printable Labels

Replacing silicon processors, smart tags that are printed collect information themselves and process it. The result of decades of research and development by ThinFilm Electronics are “printed transistors, the multilayer tags combine a year’s worth of battery power, sensors and a small display, and will initially be used to show a temperature record of perishable food and medications. Roughly 3 x 1.5 inches in size and consisting of five layers sandwiched in a roll-to-roll production process, the ThinFilm labels use the company’s own ferroelectric polymer technology for storing information. Chains of non-toxic polymers can be flipped between two orientations – representing binary “0″ and “1″ – to store non-volatile data.”

Electronic Labels

While price increases when labels are electronic, the very small percentage of labels that are electric is increasing. Electronic labels have features that supersede non-electronic labels. Electronic versions can signal what is happening in real-time and most can store a digital record.

s. The application directly to the product is still of neglectible importance * due to the cost of the labels, which may be justified easier for agglomerations of more than one product * because all metallic, liquid or otherwise electrically not transparent products reflect or reduce the radio waves * due to the handling, which normally addresses the package and lesser the unpacked product.

. With increasing sales quantities, the inlays are still annually redesigned and appear in releases with new extensions to performance. However, the integration of RFID to handling processes requires sound engineering to ensure the balance of benefit and effort. In 2008, ThinFilm and Polyera announced their partnership to produce high volumes of smart labels. The collaboration brings printed integrated systems, such as smart sensor tags, closer to commercial availability.
