Radio Frequency Identification Tags (RFIDs)

Hello frnds, have u heard about RFIDs.....in this post i am going to tell u about Radio Frequency Identification Tags (RFIDs) and give a brief comparison between Silicon and Organic RFIDs. Actually, RFID tag is a wireless form of automated identification technology that allows non-contact reading of data, making it effective for manufacturing, inventory, and transport environments where bar code labels are inadequate.

Advantages of organic-based RFID tags over silicon-based tags include mechanical flexibility (e.g., bendable) and direct fabrication onto large area substrates using simple printable methods. 

The attractiveness of printed organic semiconductor materials and manufacturing platforms has drawn the involvement of several companies(e.g.,3M,Siemens),start-ups(e.g.,OrganicID,ORFIDCorp.),and research institutions to develop technology for organic-based RFID tags. For example, a 64-bit inductively-coupled passive RFID tag on a plastic substrate was demonstrated, operating at 13.56MHz and with a read distance of over 10 cm.

These specifications are approaching item-level tagging requirements, paving the way for low-cost high-volume production of RFID tags, with the potential to replace barcodes.
