How To Make A QR Business Card and Never Run Out of Cards

This idea comes from cosplaying and that sometimes a costume does not have pockets to store the business cards that you would be giving or receiving. I took this concept from wearable QR codes (which would contain contact information) and added this QR to my business card holder.

The QR labels are waterproof thermal labels and are basically indestructible.

I have never run out of cards, even when I have no more physical cards to give to people.

I added it to both sides.
