@xodium If you have the space, you can print out a 1-pager with all the info you want to share.
However... most people don't read them. As I often had to point to the sign (especially after my voice was horse after the 1st day of the show). But it does give basic details + a QR code for more info, etc.
Having these as a digital file on the device is neat, but if people don't read them while they're IRL, they may not bother to click on them to read them. Good luck!
