                              5.2.2 CURRENT PRACTICES
                              The advent of scanning has introduced a new set of variables into the identifi-
                              cation process. In addition to the information contained on the physical fin-
                              gerprint card, information is extracted from or added to the record through
                              electronic processing. Card scanning and livescan are the primary scanning
                              techniques.


                              5.2.2.1 Card Scanning
                              In card scanning, the information on the fingerprint card is converted into
                              electronic media and can be transmitted over communication lines to AFIS
                              using an FBI-certified scanner. This produces a high-quality image similar to
                              that obtained from a high-end fax or copy machine. Although card scan images
                              are clearer than the fax machine images they replaced, they may not contain
                              the clarity and definition of livescan images or inked tenprint cards. Still, card
                              scanning is a relatively inexpensive method for transmitting the finger images
                              contained in the 14 image boxes on the card.
                                 The arrest and pedigree information may come from another source, such
                              as the OLBS. Care must be taken to ensure that the OLBS information matches
                              the images transmitted, and that the card scan device is properly maintained.
                              As with every device, proper training is required for optimum results.
                                 Because the accurate capture and transmission of images is critical to the
                              identification process, the FBI has developed an Image Quality Specification
                              (IQS) for card scanners as well as livescan devices, fingerprint card printers,
                              and other integrated products. To communicate with the FBI, agencies must
                              use a device that has met their specifications and that appears on the FBI’s list
                              of certified products. 2


                              5.2.2.2 Livescan
                              Livescan is rapidly replacing inked tenprint cards as the preferred input device.
                              Livescan stations are available from each of the major AFIS vendors, as well as
                              directly from manufacturers who will integrate the livescan units into the AFIS
                              systems. The livescan device pictured in Figure 5.8 is typical of the devices on
                              the market.
