Are QR Codes Really More Easily Read by Computers

Yes, proof UPS,FEX ED, and etc all use them.

QRcode are simple patte of binary values either a 1(black) or 0(white) and that is it. The squares can be bigger or smaller, but you still have a 2 digit alphabet. There are no different fonts,styles, or anything. Also because they are so uniform sizes can be auto-detected. They also built-in error checking which is never done,sure spell check can help on text but sometimes it also causes errors, with individual letters when typing or handwriting. If the checksum doesn't balance you read the code wrong, try again. Most QRcode also have alignment squares to make sure the computer rotates them into near perfect alignment before reading them.

Typed text has these complexities that QRcodes don't.

• 96+ foreign letter symbols. (Unicode!)
• many different size
• 1000's of fonts, lets can be vastly different in each font.
• different colors
• types like bold,italic,underline

Handwriting adds even more complexities:

Each one of our handwriting is so unique specialist exist for banks that use that to determine forged checks and alter documents to reasonable certainty.

All of the complexities mean it is way slower, and less accurate. In many business, like FEDEX time in small increments is big money. They literally read millions of barcodes a day, and even if it was only 1 second longer to translate 1 second times a million barcodes is a lot of time wasted.
