Think all 2D barcodes are just QR codes? In this quick demo, Sean and Chris put the new SparkFun 2D Barcode Scanner to the test by scanning QR codes, Data Matrix codes, and PDF417 barcodes to see what makes each one different. Turns out, they're not all the same.

they all have advantages and disadvantages. pdf 417 is very durable and secure from tampering, so it's good for things like shipping labels or airline boarding passes. QR can hold more data. datamatrix can be made really small.
*Fun Fact:* The primary difference between QR code’s and barcodes is that a barcode must be read horizontally, has a maximum storage capacity of 12 - 43 characters (e.g. universal product code etc.), and can store data in one dimension, whilst a QR code is capable of being read horizontally and vertically, has a maximum storage capacity of 4000 - 7089 characters, and can store data in two dimensions as a matrix bar code. Additionally, a QR code can be 10x smaller than a bar code and still be legible and a QR code can be read if damaged or parts missing. The term “QR code” is an abbreviation for “quick response code” If even a single person learns from this, my time will not have been wasted 🤔
All languages are languages even tho they sound diffrent have have diffrent rules kinda like Dutch is just drunk german
“Aren’t all of these just glorified qr codes” No, qr codes are glorified these
It’s actually matrices. Not “matrixes”
Qr codes have 3 markers to determine orientation. Data matrix is pure data. Christmas trees here use 3d data. So the color is important..
honestly "data matrix" sounds valid for all those forms
nifty little board you got there
whats the resolution on that thing. If you scan a full page qr code, how much data can it read before the dots are too small to work?
matrices
I guess one day soon we'll ALL be tattooed with ONE of them... 😯
And not a single one Rick Rolled him.
Will be replacing Children in near future..
Yeah they are all QR codes in the sense that the word now means anything that can scanned like that for information
This guy is a Redditor, confirmed.
glorified qr code... yup... and QR codes are just glorified bar codes
The phone can do that. God technology is overly complex for no reason.
LMFAO the end
Nice Sac Republic kit
might just be my next project ngl
