After the NFC CARD display Polymer Vision and the recent demonstration of the memory capacity of some polymers, plastic RFID tags represent the third field of application of organic electronics developed by Philips.
"The production of low-cost RFID tags is one of the fundamental objectives to be pursued to make the benefits of this technology within the reach of everyone," he told Computer Point Patierno Corrado, Italian expert in the field: "The production process in a single being developed by Philips costribuisce certainly drive down manufacturing costs of the tag. "
It must be said as well as the German PolyIC is collaborating with Lufthansa for about two years for the development of plastic RFID tags to be used in aeronautical field (logistics, tiketing, security). combo cards
Hitachi has instead announced the development of the world's smallest RFID chip, with dimensions of 0.15 square millimeters and a thickness of 7.5 microns. Compared with the previous version (0.30 mm2 x 60 m), the surface was reduced to a quarter.
These chippetti lend themselves particularly well to be inserted inside the card, and then tickets or even banknotes.
The Japanese giant claims that the new production technique allows to triple the yield per single wafer, resulting in a reduction of costs. Currently chips have a capacity of 128 bits, operate in the frequency range of 2.45 GHz, and possess a unique identification code stored in ROM.
Hitachi is also working to increase the reading distance and reduce the size of the antenna (off-chip). the goal is to get to production of a small chip technology with the "double side electrode" percreare tag of small size with integrated antenna.
"Presumably, for the production of chips with integrated antenna, Hitachi will migrate from 2.45 to 5.4 GHz using UWB (Ultra Wide Band), which allows the transmission of energy with micro-pulse-on a broader spectrum of frequency, "said Patierno. "Hardly, however, we can expect that allow microscopic tag readings at a distance greater than a centimeter (already a great achievement!) Because, as explained in my in-depth articles on RFID, the reading distance and power transmit / receive are a function of size antenna: so much smaller, much less the tags will be performing. remember also that in Italy and in many European Union states that the frequencies used by Hitachi is not poss.contactless cards
