Hi everyone! Today I was writing some Christmas postcards for swap and I wanted to include my favorite Christmas song on the card. I thought that I could print off a QR code and stick it on the card, with a link in it to the song. I was thinking of other uses of this, so if anyone has any other cool idea, let me know!
Have a great day!

What a cool idea! 
I’ve sent a birthday song to my cousin this way 
I also used a binary code to encrypt short wishes, I think is a good idea for someone interested in IT.
Another extraordinary thing: writing in Latin, using eg. Google Translate (hopefully without glaring mistakes…)

This sounds like a really fun way to share social media accounts, videos, and memes! Or you could write longer messages and put the QR code for someone to see their personalized message
