Hi, For a specific project I am looking for a RFID active tag chip, but with both contactless and wired connectivity.
Basically I want to design a RFID tag, but with an on-board microcontroller which should be able to change the content of the RFID tag based on external events, through a I2C link or similar. Do you know products or chips that could implement this functionnality ?
Frequency range probably in the 13MHz or 860MHz bands.
Many thanks, Robert Lacoste
