alphadogg writes: Charles Walton, inventor of the RFID technology now common everywhere from warehouses to retail stores to public libraries, has died at the age of 89 in California. Walton, whose technology beat out barcodes for many applications and is paving the way for technologies such as near-field communications (NFC), died on Nov. 6 and a memorial service will be held Dec. 18 in Los Gatos.
