1D barcodes typically encode between 5 and 60 characters; you are unlikely to use one with more than 100 encoded characters.
2D barcodes can encode considerably more characters, ranging from a few characters to several thousand.
[I think that PDF417 will cater for up to about 1800 characters or so; DataMatrix will do somewhere around 4000]
Some of the 2D codes (e.g. PDF417) can be encoded so that you can 'stitch together' a series of individual barcodes to provide a larger overall code.
But you're still probably only dealing with a maximum of about 10KB-20KB in the most extreme case.
