Putting Security First

In addition to the old faithfuls, new tamper-apparent devices are hitting the marketplace like Nanoventions' (Roswell, Ga.) Conseal, which uses micro-optics to protect packages. When intact, Conseal can display information or appear like a clear tape. But once the label is disturbed, the two layers of the security device separate to reveal a message. "If it's been tampered with, it's essentially impossible to put it back together again," said Nanoventions CTO Rick Steenblik.
