Amazing: a True Type QR Code font. Type text and it converts into a pure text QR code. All the magic happens within the OpenType layer. https://qr.jim.sh/ #qrcode #fonts

QR Codes in Education: Advancing Digital Inclusion and Educational Equity for Marginalized Communities

To keep the blog readable and visually engaging, each theme should be paired with its own image section. Here’s a structure you can use:

QR Codes in Education: 19 Ways to Empower Marginalized Communities Through Digital Inclusion

Introduction

QR codes are transforming education by connecting learners to digital resources instantly. For marginalized communities, they can help bridge gaps in access, affordability, and opportunity.

Theme 1: Digital Inclusion for All

QR codes provide instant access to learning materials, helping underserved learners connect with educational opportunities.

Theme 2: Supporting Rural Education

Rural schools can use QR codes to access updated educational resources beyond what is available in physical classrooms.

Theme 3: Reducing Educational Costs

Digital content linked through QR codes reduces printing and textbook costs.

Theme 4: Open-Source Solutions for Education

Free tools like LibreOffice make QR code creation accessible to all schools.

Theme 5: Enhancing Library Services

Libraries can use QR codes to connect users to catalogues, e-books, and research guides.

Theme 6: Inclusive Education for Learners with Disabilities

QR codes can link learners to audio books, captions, and accessible content.

Theme 7: Mobile Learning Opportunities

Mobile phones become powerful educational tools through QR code access.

Theme 8: Supporting Multilingual Learning

QR codes can provide educational content in multiple languages.

Theme 9: Strengthening Digital Literacy

Using QR codes helps learners develop digital navigation skills.

Theme 10: Connecting Physical and Digital Learning

Printed materials become interactive through QR-linked content.

Theme 11: Supporting Refugees and Displaced Learners

QR codes can quickly distribute educational resources where infrastructure is limited.

Theme 12: Encouraging Independent Learning

Learners gain flexibility to study at their own pace.

Theme 13: Improving Teacher-Student Communication

QR codes simplify the sharing of assignments and announcements.

Theme 14: Access to Open Educational Resources

Students can access high-quality educational materials for free.

Theme 15: Supporting STEM Education

QR codes provide instant access to simulations, coding tutorials, and experiments.

Theme 16: Building Community Learning Networks

Schools, libraries, and community centers can share resources through QR codes.

Theme 17: Promoting Lifelong Learning

Falls der QR-code auch irgendwo öffentlich ausgehängt werden soll:
QR-codes sind praktisch, aber man kann bekanntlich auch 'falsche' links zu bösartigen Seiten zB in überklebten QR-codes reinschmuggeln.
Um die Nutzer davon zu schützen, und ihr Vertrauen zu gewinnen: der obige link als Text lesbar unter den QR-code, dann kann jede:r nach scan verifizieren, BEVOR die Seite geöffnet wird (entsprechende Einstellung in Scanner App!)

Releasing Barcoder 0.5.0

Finally a release, which I think could be truly useful to people out there. This time you can have a vector image as output.

Sounds like a small thing, right? But remember when you for the last time tried to resize a QR code onto a document you've made and it was all blurry and ugly. NOT WITH this app!

So if you work in a field, where you need barcodes or eventually QR codes grab it from Flathub...

This is something that came up while designing my business card.

I included a #QRCode to my website, as well as the plain URL. I realize that many people see QR codes as a security risk and refuse to use them, and I can understand that. However, many others like them for their convenience. So I was wondering what your stance on them is.

The #internet is getting impossible to use with all the #Enshittification. Having a secure computer, using #vpn, #adblock, and a #secure #browser for #privacy results in a #Google #qrcode all over the place. I will never play these games. When The Enshittifiers implement ID uploads to use a computer or the internet, then I’m done.

La #privacy e la #sicurezza in treno non dipende solo dalle infrastrutture.

I treni di un tempo avevano scompartimenti chiusi, si chiacchierava e nessun passante era in grado di cogliere le conversazioni - a meno di non origliare dalla porta a vetro o forare il pannello di separazione tra gli scompartimenti.

Oggi vale la formula "+ passeggeri = + posti, + spazio a sedere, - privacy"; certamente utile per le compagnie, che si assicurano di fornire connettività (tramite registrazione email, OTP via SMS o #QRCode) per permettere a tutti, in ogni momento del viaggio, di raccontare i fatti loro all'interlocutore e a tutti i passeggeri vicini.

La comodità dei tavolinetti (sul quale ho appoggiato il mio computer per scrivere questo post) è un'arma a doppio taglio. Perché se il signore asiatico a fianco sta doomscrollando Instagram, la sua signora sta giocando al sudoku, la teutonica sta facendo check-in del suo BnB a Venezia, altri stanno guardando Facebook, IG, cercando notizie, guardando film e serie, ecco, la persona davanti a me sta utilizzando chatGPT e mandando messaggi su TG a tutto il mondo.

Studente, sta completando parti di uno studio con l'#AI, fa screen e copia-incolla pezzi in un gruppo WhatsApp (su Mac), scrivendo con il cellulare altri messaggi.

Vedo ogni messaggio che manda, vedo i numeri delle persone alle quali (non contatti suoi) sta scrivendo), vedo i prompt (non ci siamo... puoi migliorare), e potrei facilmente inserirmi sul suo AirDrop.

Le obiezioni "eh ma allora non si può fare niente che tu critichi!", come sempre, le archivio ordinatamente (mira la vastità) e appendo il cartello: se non stai attento alla tua privacy, la colpa non è mia che leggo quello che lasci in bella mostra.

Che fare?
Se proprio non potete fare a meno, usate uno schermo per la privacy su telefono e computer, abbassate la luminosità, fate un rapido controllo di chi vi siede accanto, dietro, di lato. Abbassate la tendina per evitare riflessi.

Piuttosto improbabile che il lavoro della persona davanti sia military-grade, quindi non si evidenziano problematiche.
Ma quando lavorate con documenti ed informazioni sensibili, fate molta attenzione.

Perché basta un niente che un cattivo, o una stronza seduta dietro, veda e utilizzi i dati che lasciate incontrollati.

Ripeto: non succede niente se lavorate alla tesi, nemmeno se prenotate una macchina pagando in anticipo con la CC, ma siate consapevoli che esponete pezzetti della vostra vita.

Essere in grado di ricostruire questi pezzetti, metterli in fila e usarli, è una risorsa per qualcuno.
E ci sono altri qualcuno disposti a pagare per queste risorse.

Fate attenzione.
Sempre.

@PedestrianError i could be wrong and I can't speak for all smartphone platforms, but my understanding is that iOS decodes a #QRCode locally. Its only if you click the link in, say, Camera that it pings the site. No idea whether Apple is logging it, but the tool *shouldnt* hit the endpoint if you, say, accidentally scan an untrusted QR Code.

In this specific case, the qr code loads up a direct link to Colin's URL, not a shortened, intermediary link. QR Codes that go to directly to the event-runner's website would, I think, be the safest way to check if the QR code in question is more privacy conscious.

I get being #privacy conscious and hope sharing my thinking here helps - the utility of qr codes is high, and we can be good privacy advocates by suggesting steps that educate the reader.

Anyway - nice to chat with you (not sure if we have interacted before, hi!)

Any recommendations for this?

I have an interesting situation. I need #businesscards -- but I have a specific need.  I need to be able to add a #QRcode to the cards.

Has anyone used a particularly good #service / #printer for this type of thing? Or is just someplace like Vista Print the best bet?

So, this is becoming more of a thing, I see. We are being pushed to use our phone to "prove we are human", to access services.

The "mobile device" contains the number of our name. It will not be long and no one will be able to buy or sell without this number, or the name of the beast, or the mark of the beast.

Das neue System zeigt keine zerstückelten Bilder oder verzogenen Wörter, sondern einen QR-Code. Diesen muss man mit einem Mobiltelefon scannen, auf welchem man mit seinem Google-Konto eingeloggt ist. Damit wird eine noch viel stärkere Verbindung zwischen dem eigenen Google-Konto und der besuchten Webseite hergestellt.
