Two-Dimensional Bar Code Overview - Dataintro

PDF417 is a high-capacity two dimensional bar code developed by Symbol Technologies, Inc. A PDF417 symbol can hold approximately 2000 characters of information, whereas a traditional linear bar code has difficulty holding more than 30 characters. The key characteristic of PDF417 is its large information capacity. This also explains its name.
