I mean, you may think your <a href="http://moo.com" rel="nofollow noopener" target="_blank">moo mini-cards</a> are pretty funky - but they're nothing without a QR code.Why do you hand your card over to someone? You want the recipient to plug your contact details into their address book, right? So you give them a bit of card and then you expect them to tap away on their phone, like a primitive ape, until they've saved your number. And hope they've saved it correctly.That's just so.... analogue... Isn't there a better way of doing things?Yes. Yes there is. QR Codes are here and they are going to ROCK YOUR WORLD!Introducing QR CodesQR Codes are two dimensional barcodes which can quickly and easily be scanned by most camera phones. They're free to create, easy to use, and they look like this.Go take a look in your phone's app store - you'll find several free readers. If you can't, point your phone to <a href="http://GetReader.com/" rel="nofollow noopener" target="_blank">GetReader.com</a> to see what's available for your device.QR Codes can contain many different types of data - URL, phone number, SMS, and vCard. I'm going to show you how you can integrate these into your Moo Cards.URLWith a QR code on your Moo Card, you can point people straight to your blog.To your .tel website.Or any other site you like. Perhaps to search Twitter for your hashtag?Phone NumberScanning in this code will prompt your phone to give me a call. Why not leave me a message?SMSWant someone to scan your card and send you a message? Dead easy.vCardScan this code and my address will appear in your phonebook as if by magicOne thing to note is that these QR codes are rather large - it's probably best to print them on full size cards.Putting It All TogetherHere are some of my cards. I've used free or Creative-Commons images of phones and placed the QR code inside them.ResourcesThere are several free sites you can use to create your QR Codes.I recommend using <a href="http://www.qrstuff.com/" rel="nofollow noopener" target="_blank">QRstuff</a> to generate these codes.You can also use <a href="https://web.archive.org/web/20110721040646/http://code.google.com/apis/chart/image/docs/gallery/qr_codes.html" rel="nofollow noopener" target="_blank">Google Charts for QR Codes</a> if you want dynamic, highly customised codes.Finally, if you want to generate QR codes on your own site, there are several free resources. I use Swetake's <a href="https://www.swetake.com/qrcode/" rel="nofollow noopener" target="_blank">QRCode v0.50</a>.Final TipsHere are some tips to make sure you get the most out of your QR codes.<ul><li>Use black ink on a white background to ensure the code is readable.</li><li>Ensure there is some whitespace around the code.</li><li>If you resize the QR codes, don't use any interpolation.</li><li>QR Codes can have variable error-correction. Unless your codes are likely to get dirty, you can set this to "low".</li><li>If you're pointing people to a URL, make sure it's mobile friendly.</li><li>Make sure your phone numbers are in International Format (+44 for the UK).</li><li>Be creative!

Flippin' 'eck, Tucker!<a href="https://mastodon.social/@glynmoody" class="u-url mention" rel="nofollow noopener" target="_blank">@glynmoody</a> Like so many things it's not really the technology that's at fault. QR codes are a convenient way of encoding & transmitting information.The problems are that (a) most phones are configured to automatically load the webpage pointed at by a QR Code (assuming it encodes a URL) and (b) the persistent problem behind almost all online scams -- users are not given the tools or knowledge to help them detect a fraud.I use <a href="https://secuso.aifb.kit.edu/english/" rel="nofollow noopener" target="_blank">the SECUSO QR Scanner app</a> on my phone which not only displays the URL before launching it, but requires the user to check a confirmation box forcing you to think a bit more about what's about to happen.Of course that only solves problem (a) above.<a href="https://social.chatty.monster/tags/QRcodes" class="mention hashtag" rel="nofollow noopener" target="_blank">#QRcodes</a>

Terence Eden’s BlogA Recursive QR Code<a href="https://shkspr.mobi/blog/2025/03/a-recursive-qr-code/" rel="nofollow noopener" translate="no" target="_blank">https://shkspr.mobi/blog/2025/03/a-recursive-qr-code/</a>I've been thinking about fun little artistic things to do with QR codes. What if each individual pixel were a QR code?There's two fundamental problems with that idea. Firstly, a QR code needs whitespace around it in order to be scanned properly.So I focussed on the top left positional marker. There's plenty of whitespace there.Secondly, because QR codes contain a lot of white pixels inside them, scaling down the code usually results in a grey square - which is unlikely to be recognised as a black pixel when scanning.So I cheated! I made the smaller code transparent and gradually increased its opacity as it grows larger.I took a Version 2 QR code - which is 25px wide. With a 2px whitespace border around it, that makes 29px * 29px.Blow it up to 2900px * 2900px. That will be the base image.Take the original 25px code and blow it up to the size of the new marker, 300px * 300px. Place it on a new transparent canvas the size of the base image, and place it where the marker is - 400px from the top and left.Next step is creating the image sequence for zooming in. The aim is to move in to the target area, then directly zoom in.The whole code, if you want to build one yourself, is:<pre><code>#!/bin/bash# Input fileinput="25.png"# Add a whitespace borderconvert "$input" -bordercolor white -border 2 29.png# Upscaled image sizeupscaled_size=2900# Scale it up for the baseconvert 29.png -scale "${upscaled_size}x${upscaled_size}"\! base.png# Create the overlayconvert -size "${upscaled_size}x${upscaled_size}" xc:none canvas.pngconvert "$input" -scale 300x300\! 300.pngconvert canvas.png 300.png -geometry +400+400 -composite overlay.png# Start crop size (full image) and end crop size (target region)start_crop=$upscaled_sizeend_crop=350# Zoom-in target position (top-left corner)target_x=375target_y=375# Start with a completely opaque imageoriginal_opacity=0# Number of intermediate imagessteps=100for i in $(seq 0 $((steps - 1))); do # Calculate current crop size crop_size=$(echo "$start_crop - ($start_crop - $end_crop) * $i / ($steps - 1)" | bc) crop_size=$(printf "%.0f" "$crop_size") # Round to nearest integer # Keep zoom centered on the target crop_x_offset=$(echo "$target_x - ($crop_size - $end_crop) / 2" | bc) crop_y_offset=$(echo "$target_y - ($crop_size - $end_crop) / 2" | bc) # Once centred, zoom in normally if (( crop_x_offset < 0 )); then crop_x_offset=0; fi if (( crop_y_offset < 0 )); then crop_y_offset=0; fi # Generate output filenames background_file=$(printf "%s_%03d.png" "background" "$i") overlay_file=$(printf "%s_%03d.png" "overlay" "$i") combined_file=$(printf "%s_%03d.png" "combined" "$i") # Crop and resize the base convert "base.png" -crop "${crop_size}x${crop_size}+${crop_x_offset}+${crop_y_offset}" \ -resize "${upscaled_size}x${upscaled_size}" \ "$background_file" # Transparancy for the overlay opacity=$(echo "$original_opacity + 0.01 * $i" | bc) # Crop and resize the overlay convert "overlay.png" -alpha on -channel A -evaluate multiply "$opacity" \ -crop "${crop_size}x${crop_size}+${crop_x_offset}+${crop_y_offset}" \ -resize "${upscaled_size}x${upscaled_size}" \ "$overlay_file" # Combine the two files convert "$background_file" "$overlay_file" -composite "$combined_file"done# Create a 25fps video, scaled to 1024pxffmpeg -framerate 25 -i combined_%03d.png -vf "scale=1024:1024" -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p recursive.mp4</code></pre><a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/art/" target="_blank">#art</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/qr/" target="_blank">#qr</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://shkspr.mobi/blog/tag/qr-codes/" target="_blank">#QRCodes</a>

Terence Eden’s BlogWhy are QR Codes with capital letters smaller than QR codes with lower-case letters?<a href="https://shkspr.mobi/blog/2025/02/why-are-qr-codes-with-capital-letters-smaller-than-qr-codes-with-lower-case-letters/" rel="nofollow noopener" translate="no" target="_blank">https://shkspr.mobi/blog/2025/02/why-are-qr-codes-with-capital-letters-smaller-than-qr-codes-with-lower-case-letters/</a>Take a look at these two QR codes. Scan them if you like, I promise there's nothing dodgy in them.     Left is upper-case <code>HTTPS://EDENT.TEL/</code> and right is lower-case <code>https://edent.tel/</code>You can clearly see that the one on the left is a "smaller" QR as it has fewer bits of data in it. Both go to the same URl, the only difference is the casing.What's going on?Your first thought might be that there's a different level of error-correction. QR codes can have increasing levels of redundancy in order to make sure they can be scanned when damaged. But, in this case, they both have Low error correction.The smaller code is "Type 1" - it is 21px * 21px. The larger is "Type 2" with 25px * 25px.The <a href="https://www.qrcode.com/en/about/version.html" rel="nofollow noopener" target="_blank">official specification</a> describes the versions in more details. The smaller code should be able to hold 25 alphanumeric character. But <code>https://edent.tel/</code> is only 18 characters long. So why is it bumped into a larger code?Using a decoder like <a href="https://zxing.org/" rel="nofollow noopener" target="_blank">ZXING</a> it is possible to see the raw bytes of each code.UPPER<pre><code>20 93 1a a6 54 63 dd 28 35 1b 50 e9 3b dc 00 ec11 ec 11 </code></pre>lower:<pre><code>41 26 87 47 47 07 33 a2 f2 f6 56 46 56 e7 42 e746 56 c2 f0 ec 11 ec 11 ec 11 ec 11 ec 11 ec 11ec 11 </code></pre>You might have noticed that they both end with the same sequence: <code>ec 11</code> Those are "padding bytes" because the data needs to completely fill the QR code. But - hang on! - not only does the UPPER one safely contain the text, it also has some spare padding?The answer lies in the first couple of bytes.Once the raw bytes have been read, a QR scanner needs to know exactly what sort of code it is dealing with. <a href="https://www.thonky.com/qr-code-tutorial/data-encoding#step-3-add-the-mode-indicator" rel="nofollow noopener" target="_blank">The first four bits tell it the mode</a>. Let's convert the hex to binary and then split after the first four bits:TypeHEXBINSplitUPPER<code>20 93</code><code>00100000 10010011</code><code>0010 000010010011</code>lower<code>41 26</code><code>01000001 00100110</code><code>0100 000100100110</code>The UPPER code is <code>0010</code> which indicates it is Alphanumeric - the standard says the next 9 bits show the length of data.The lower code is <code>0100</code> which indicates it is Byte mode - the standard says the next 8 bits show the length of data.TypeHEXBINSplitUPPER<code>20 93</code><code>00100000 10010011</code><code>0010 0000 10010</code>lower<code>41 26</code><code>01000001 00100110</code><code>0100 000 10010</code>Look at that! They both have a length of <code>10010</code> which, converted to binary, is 18 - the exact length of the text.Alphanumeric users 11 bits for every two characters, Byte mode uses (you guessed it!) 8 bits per single character.But why is the lower-case code pushed into Byte mode? Isn't it using letters and number?Well, yes. But in order to store data efficiently, Alphanumeric mode only has <a href="https://www.thonky.com/qr-code-tutorial/alphanumeric-table" rel="nofollow noopener" target="_blank">a limited subset of characters available</a>. Upper-case letters, and a handful of punctuation symbols: <code>space $ % * + - . / :</code>Luckily, that's enough for a protocol, domain, and path. Sadly, no GET parameters.So, there you have it. If you want the smallest possible physical size for a QR code which contains a URl, make sure the text is all in capital letters.
