The Xenon 1900h and 1902h area-imaging scanners enable caregivers to read virtually all bar codes found in healthcare environments with ease, regardless of character size or the surface on which they are printed. Both handhelds feature a decoding architecture that combines Adaptus Imaging Technology 5.5 and Omniplanar's SwiftDecoder software to provide extended depth of field, faster reading and improved scanning performance on poor-quality bar codes.
