Package: QRCodeReader_FMX
 NameDescription
TITFReader

Implements decoding of the ITF format, or Interleaved Two of Five.

This Reader will scan ITF barcodes of certain lengths only. At the moment it reads length 6, 8, 10, 12, 14, 16, 18, 20, 24, 44 and 48 as these have appeared "in the wild". Not all lengths are scanned, especially shorter ones, to avoid false positives. This in turn is due to a lack of required checksum function.

The checksum is optional and is not applied by this Reader. The consumer of the decoded value will have to apply a checksum if required.

http://en.wikipedia.org/wiki/Interleaved_2_of_5 is a great reference for Interleaved 2 of 5 information.
