Library Workers, Patrons Denounce RFID System

More than 100 people filled the South Berkeley Senior Center Monday to debate the Berkeley Public Library’s practice of placing radio frequency identification devices (RFIDs) in books.

The library has already begun installing the $650,000 system, replacing bar codes on book covers with radio antennas. The forum, hosted by KQED’s Keven Guillory, featured dozens of library users and staff members who denounced the use of the devices.

Opponents charge that as scanners become more powerful and widespread, the technology will allow authorities to trace not just books, but library patrons as well. Others said they worried that the low level radio frequencies emitted by the tags might cause cancer. Berkeley Daily Planet has the story.
