Rocketbook QR Codes

Rocketbook QR Codes

I started using Rocketbook paper a few months ago as just generic notepaper. Most of the time I don’t scan, but it’s perfect when I do want a digital copy of whatever I scratched out. Part of that, I wanted to try and figure out the significance of the Rocketbook QR Codes.

If you’re not familiar with Rocketbooks, they started out as a rewriteable notebook. Using their app you can snap a picture and have it sent to Evernote, Google Drive, email, or one of several other destinations. They also released free PDF templates and normal paper, single use Rocketbooks are available as well.

A few days ago I started playing around with the idea of creating templates that I could use on top of the Rocketbook layout to make life a little easier. I was thinking a lesson plan template would be pretty cool.

But I needed to do a little decoding. On the bottom of each Rocketbook page is a QR code that tells the app that it’s a Rocketbook page. There’s a black border around the content of the page. And there are 7 bubbles you can fill in to tell the Rocketbook app where to send your scan. Although I’ve actually found it easier to not fill in the bubbles. Rocketbook will then prompt you for a destination and that seems easier than trying to remember what the horseshoe bubble means.

The first thing I tried was to scan a blank sheet of paper. The app didn’t read it. Then I tried a page with a thick black border. Still didn’t work. Then I tried a sheet with a black border and a QR code. Worked like a charm.

But now I want to figure out what the QR code meant, so I downloaded all of the sample PDFs they have and scanned the QR codes. The text is in the table below.

Page DescriptionQR Code String
Dot Grid: A4P01 V05 S0000000
Dot Grid: LetterP01 V04 S0000000
Goal AgreementP01 V18 T00 S000
Graph Paper: A4P01 V0P S0000000
Graph Paper: LetterP01 V0O S0000000
Lined: A4P01 V0N S0000000
Lined: LetterP01 V0M S0000000

So, here are my assumptions about the Rocketbook QR codes.

P is the page number. I was looking at their PDFs, so they’d all be page 1. I did scan an image from Amazon and the page number was different.

V is a unique string for each layout. I assume this tells the app something. Maybe paper size. For all of the examples I found it’s a V followed by a number followed by a letter, except for the Goal Agreement. It’s a V followed by 18. The letter graph paper is V, zero, oh.

No clue what the S followed by 7 zeroes is, but they were all the same except for the Goal Agreement. It had an S followed by 3 zeroes. But it also had a T followed by 2 zeroes and was the only one like that. Again, no clue what that means.

Paper Sizes

I did find out, several months after originally writing this post, that the code does have something to do with page size.

Last week I tried printing some pages that were a third of a sheet, horizontally. So, 8.5 inches tall by 3.67 inches wide. Basically, I was looking for a tall, narrow notepaper. Gave the page a wide black border and put the QR code from the downloadable letter size PDF.

It didn’t work. The app wasn’t able to lock on to the page for a scan. But, if I use the same QR code on a letter sized page or a half sheet – 8.5 inch by 5.5 inch – it will lock on to the page and scan it. Not sure if there’s anything I can do to fix that unless there is a QR code out there that is on a narrow enough page.

What’s the point?

Really, probably isn’t a good one. Mostly curiosity. The QR code value doesn’t seem to affect the scans, at least not in any meaningful way that I can see. I played around and made a few different sheets that all had the same QR code and they worked fine.

Any others?

If you’re using a Rocketbook and want to scan the QR code and share its value, leave a comment down below and I’ll add it to the table. Newsletter

  1. Hi, From my own experience, it seems P does represent page, but not the number. All P1 pages have their barcode in the bottom left (think, front of page) and P2 pages have theirs on the bottom right (think backside of P1) This is so the app knows where to look for the checked symbols/correct borders. As far as the other details, im almost certain they are all hardcoded into the app, so you wouldnt be able to just change a number to change page width for example, though that doesnt rule out the possibility of being able to reverse engineer and recode the app to take in custom varaibles. Who knows, maybe the future rocketbooks and app will allow for the width and hieght of page to be encoded into the QR code instead of Hardcoded into the app.

    1. That makes sense. I’m using the PDFs, so the QR code is always on the bottom right. And you’re probably right about the numbers being hard coded in the app.
