When I generate a QR code using the link https://express.adobe.com/tools/qr-code-generator
does that QR code work forever as long as the link still works? I am planning on using this on printed books and need to make sure the code will always work.

Hi @Adam21915573ezxs:

 

As a head up, InDesign includes the command in Object > QR Code.

And no, the InDesign QR codes don't expire. They will work as long as the URL is active.

I am never sure why it's thought that QR codes are somehow "fluid" or "dynamic" or dependent on server/net data.

 

A QR code is simply a barcode, a complex one that can encode up to several hundred characters of data while still remaining "coarse" enough to be read easily. (When the data reaches its limit, the QR pattern can be so fine that any small printing or display flaw makes it unreadable.)

 

Once generated, all the QR code has, forevermore, is the data that was encoded in it. It will rema

Once generated, all the QR code has, forevermore, is the data that was encoded in it. It will remain readable as long as it is clear enough for a suitable reader/decoder to read and decode it. It does not matter where or how it was generated.

 

The only thing that is "dynamic" about QR codes is when they actually encode an address or URL that can be redirected. Those destination addresses have to remain available, or scanning the code won't do anything useful... just as if you typed in a 'dead' web address.

 

But the codes are permanent and fixed at the moment of creation, and can only be changed by re-generating them with different embedded information.

Hi James:

 

After poking around a bit, I'm seeing references to some of the free QR generators out there putting redirects on after a set time period. Perhaps that is the source of the confusion.

 

InDesign does not do that, Adam. And including this link since you actually asked us about the Adobe Express QR generator. Note the response from the Adobe staff member.

Yeah, I assumed that some of the "free" generators are inserting their own tracking and redirection information into user URLs, so there would be a perception that the codes themselves are somehow changing or dependent on server support. Or, to be more charitable, some services may provide active, context-sensitive redirection (by time of day, for example, or to a desktop or mobile site), and not have an permanent lifespan.

QR code is like a barcode - contents doesn't change once generated, only what is on the other end can change - if it's a link to some website.

Well, a QR code can contain any sequence of characters—a URL, a passphrase or vCard information. The only real limitation on content is that too many characters will result in a very fine-grained code that may not be reliably readable. But they don't always have to contain a URL or link to any particular net destination.

 

This one contains a short story, for example. 🙂

A QR code can contain almost any valid form of data, including any valid URL pointer (such as to a product page, even using redirectors like a catalog lookup number).

 

This should have all you need to know to use ID for QR code creation: http://www.nitrosyncretic.com/DPR/dpr_qrcodes.php

 

Ask away if you still have questions.
