Frequently asked questions
What does PDF417 stand for?
Portable Data File. The 417 refers to the structure of each codeword: four bars and spaces across 17 modules.
How much can it hold?
Around 1,850 text characters, or roughly 1,100 bytes, depending on the error-correction level chosen.
Why do IDs use PDF417 rather than QR?
It stores a large structured record in a rectangle that fits a card, and the standard predates widespread QR adoption in that sector.
