I love the act of decoding symbols for my own enjoyment! 
which symbols do you decode?
Reading
Reading is the complex cognitive process of decoding symbols to derive meaning. It is a form of language processing.
Success in this process is measured as "reading comprehension". Reading is a means for language acquisition, communication, and sharing information and ideas. The symbols are typically visual (written or printed) but may be tactile (Braille).

These chargebacks can reduce a manufacturer's revenue by 2% to 10%.
A barcode verifier works the way a reader does, but instead of simply decoding a barcode, a verifier performs a series of tests. For linear barcodes these tests are:
- Edge determination
- Minimum reflectance
- Symbol contrast
- Minimum edge contrast
- Modulation
- Defects
- Decode
- Decodability
2D matrix symbols look at the parameters:
- Symbol contrast
- Modulation
- Decode
- Unused
