The 1660 pocket-size scanner is CipherLab's handiest solution, combining the features you need in a pocket-size scanner. Smaller than a mobile phone, the 1660 BT scanner packs a lot of scanning power in a small mobile package. Built-in BT allows instant data scanning to a BT-compatible PDA, notepad PC or any BT device. It continually operates through multiple shifts on a pair of replaceable AAA batteries, never interrupting work for a recharge. And when you're out of BT range, 256k of on-board memory holds hundreds of scans until you're back in range.
