A 128b organic RFID transponder chip, including Manchester encoding and ALOHA anti-collision protocol, operating with a data rate of 1529b/s

Research towards 13.56 MHz organic RFID tags is one of the drivers for the field of organic electronics. This work presents significant increases in complexity in organic RFID transponder chips compared to earlier reports, which bring the tag closer to electronic product coding (EPC). We show a transponder chip with a ROM memory capacity of 128 b. Furthermore, it contains a WORM memory in addition to the ROM. The data rate is doubled, to 2 kb/s and is Manchester encoded. Also a basic anti-collision protocol has been added, whereby the readout of multiple organic RFID tags would be possible.
