3M displayed a prototype of a combination laser scanner and library security sensor at the ALA Conference. The device allows an operator to scan a label on the outside of a book and to sensitize or desensitize a target inside the book--all in one motion. The unit uses a standard RS-232 interface, thus making it possible to connect to any local library system. The combination unit is expected to cost no more than separate components. Product release is expected before the end of 1990.
