Idea​

We developed a broadcasting service that can transfer compressed data using a series of QR codes. It's like playing a high-tech game of pass-the-parcel, but with data.

Solution​

  1. Data is compressed and split into chunks
  2. Each chunk is converted into a QR code
  3. QR codes are displayed in sequence
  4. Receiving device scans the QR codes and reconstructs the data

Impact​

  • Sharing information in areas with no internet connectivity
  • Secure data transfer without using traditional networks
  • Interactive museum exhibits or educational tools
