Ask The Experts ForumFrom Whom Can I Obtain 2.45 GHz Passive RFID Tags and Readers?I found an article on your website saying to send an email to know more about passive 2.45 GHz systems. Could you please send me some information? —Johann ——— Johann, As I stated in my reply to another reader's very similar inquiry (see Where Can I Find Passive 2.45 GHz Tags and Readers?), Hitachi's µ-chip is one of the few passive 2.45 GHz tags on the market (see Hitachi Unveils Smallest RFID Chip, Hitachi Unveils Integrated RFID Tag and Hitachi Shrinks Smallest RFID Chip). I do not know if the chip is still being marketed, as I have not seen any news about it from Hitachi in years. My previous article stated that I knew someone who had some readers to sell, but those are long gone. NXP Semiconductors made a chip that worked at 860 MHz to 960 MHz and 2.45 GHz, but I don't know if that company still sells the chip, or if anyone makes tags using it. You would need to contact NXP. BayNexus made a handheld reader that read 2.45 GHz tag (see Where Can I Find 2.45 GHz RFID Tags and Readers?). Again, however, I don't know if it is still for sale. In the RFID world, 2.45 GHz has not caught on with users. Sorry I can't be of more help. —Mark Roberti, Founder and Editor, RFID Journal Login and post your comment!Not a member?
