SF Public Library revives plan to install microchips in books
deploy radio frequency identification tags in books. Now, head librarian Luis Herrera is trying once again. Herrera disclosed the renewed effort for RFID during a Library Commission hearing and promised to return with more details in the coming weeks. That means funding for RFID — tiny microchips that exchange data with readers by emitting radio signals — could be included in the library’s budget proposal for the upcoming fiscal year.
