How to Create and Scan QR Codes


Hi, this is Jennifer Gonzalez for Cult of
Pedagogy. In this video I’m going to show you how to
create QR codes. That is what a QR code looks like. Let’s go. So I’m making this video for my book, The
Teacher’s Guide to Tech, and in that book I feature over a
hundred different technology tools. And for each one, I link the reader to a good video that’s
online that shows them the features of that tool, except I couldn’t find any that I really liked for QR codes so I decided to just make my own. Now there are a lot of QR code generators out there, but once you’ve watched this you’ll
understand how they’re made and you could basically take this same set of skills
and apply it to any other QR code generator, because it’s super super easy. So basically what a QR code is, is this: It is this picture right here and when somebody scans that with their
phone or an iPad or another device that has a
QR code reader in it, it will take them automatically to
either a website or to some other place that you’ve told
it to go. Whatever you have associated with this it’s automatically generated.
It’s a lot like a bar code that has a price embedded in it, and a — and the name of a product or whatever at
the grocery store. So let me show you how it works. Right along the side here they’re giving you a lot of different things that you can
actually plug into this QR code. So I’m going to put a URL in. I’m gonna put the URL
of my own website. Now you’ll notice that the QR code
changed when I did that. That QR code now is uniquely associated
with the URL to my own website. So what I do now is I’m going to save this
picture and I’m going to download it to my own desktop, and then I can use it
wherever I want, I just treat it like it’s a picture. So they give me a lot of different size
options. I can make it bigger or smaller. So I’ll just choose this 200
pixels and then I’m going to click Save. I want to name it something that I
remember what it is so I’ll call it “culturl.” And they give you three
choices for file types I would say just choose PNG unless you
know what these others are. PNG is just a similar to a JPEG file, but it’s more for, like, non-photographs,
other types of images, and it’s just a really common file
extension. So just stick with that, click Save… and see, it just downloaded. Okay so I just open the file, I can do whatever I want to do with this now. I can paste it
into a Word document, I can put it into a PowerPoint, I can
print it, I can print off multiple copies and hang
it on a wall. I can do whatever I want to do with it. But what’s great is that if anybody
takes their phone and scans it with a QR scanner, it will automatically do that. So suppose I am out on the street advertising my website
and I want people to come and see it. I can just say here, hold up, hold up your phone to this
QR code and you’ll go right to it. I don’t have to stand there and say it’s www.cultofpedagogy.com and have them try to spell all that
right. They wil be taken directly to it. Let me show you what other things you
can plug into a QR code. You can plug in just free text — let me just
type “I love you.” Now what happens is that when someone scans that with the QR code, they’re just
going to get basically a screen that has that text on it. So people can use this for — One thing I think of a lot is when you have
sort of an exhibit, like a gallery exhibit or something,
maybe an art exhibit and you want to code in there information about the author. And so you could put — almost like they do
in art galleries have — those little signs underneath that tells you about the author. They can have that come up, so you can
have free text come up. You can have contact information. See I’ve plugged in John Doe, [email protected] What will happen when somebody scans that is that it will scan it and then their
phone will automatically go to their contacts list and say, do you want to add
this as a contact, yes or no? It’s got all the
information all plugged in and ready, you just give it the okay. You could just plug the phone number in
and then the phone would actually go go to that phone number and it would ask
you what you want to do with the phone number, do you want to dial it? Do you want to send the person a
text? Whatever. It’s not going to automatically make the phone start to actually call. SMS basically stands for text message so what you could do is you could put
your own phone number in there and even put in an automatic text
message that says, “Hi. I attended parent night.” And maybe this is something
where you you want parents to send you a text
message when they come to parent night so that
you can get their number into your phone and this just has them automatically
send it. So there are a bunch of different things
that you can do with QR codes, but this just shows you how to make them. You just go to anything
that’s a QR code generator, you plug in your information — now one
thing it’s important to know is that each of these is something different I’m
not loading all of this information into the same QR code these are just
different things that you can create a QR code for. So that’s important
to know. Okay so I just want to show you how the QR code reader works on a phone. So this is the screen on my
cell phone and I’ve got this program right here called a QR Code Reader so
I’m going to just open that up, and basically it’s super simple it just
gives you the sort of “reading” screen. So now what I’m going to do is I’m going to
read the QR code a QR code that I made that basically
takes, is supposed to take people to my website, cultofpedagogy.com. So now I’m going to take my phone and I’m going to aim it — oh, that was so fast I barely even aimed it. And what it says here is, it’s going to open that URL. So I click
OK, and I am automatically loading up my website. The first time I did this — there, see — first time I did this, I started
jumping around. I couldn’t believe how fast it was. That is it. That’s how it works.
