There are tons of new technology show up everyday. What interests me the most (today) is: "A lot is riding on cutting-edge technology to thwart the counterfeiting of money, gift vouchers, passports, and other documents. But as quickly as scientists can develop special inks, labels, or holograms, crooks manage to up the ante. Now, Hitachi Ltd., a top Japanese chipmaker, says it has a minuscule integrated circuit that could really make things hard for counterfeiters. Hitachi's so-called meu-chips measure just 0.4 millimeters on each side--small enough to be embedded in currency and most other cloth or paper documents. The chips' read-only memory can store 128 bits' worth of identifying code, which could be used for any kind of digital serial number or a user I.D. The chips also contain wireless communications circuitry that will let them talk to a reading device up to 12 in. away over a 2.45-gigahertz band. Hitachi plans to market the first batch of meu-chips next spring.
