Extra course material, reminders, diagrams, summary sheets: everything the textbook can't hold.

School textbook, training manual or operating guide: a QR code next to each lesson opens a JeliCard with everything that doesn't fit in the book: extra course material, videos, worked exercises, past exam papers. And the author updates it whenever they wish.
Pages are limited: you have to choose between the lesson, the exercises and the answers, and everything is fixed until the next edition.

Extra course material, reminders, diagrams, summary sheets: everything the textbook can't hold.
Extra exercises with detailed answers, as photos or as a link to the file.
Papers from previous years, fully worked through, with their answers.
Experiments, demonstrations, animated diagrams, foreign-language lessons with pronunciation.
For training manuals and operating guides: video demonstrations, practical sheets.
A JeliCard is shared in one move: by text message, on social media, by email, on the internet, or simply by scanning the QR code from one phone to another. Your message travels across time and distance, and reaches every audience, here and elsewhere.
Start with one chapter, then the whole textbook.
The textbook gives the lesson. The JeliCard adds everything else, and stays up to date.
Your first JeliCard is ready in a few minutes.
