Toss-up between the logo and full text variants. Might have to flip a coin to choose.

For the QR logo, either the back or the front, under the SN logo/text.

In the back, anyone can try scanning it without me knowing. In the front it's more obvious if they try, so it would be invite-only haha

ahaha, such a great idea... we can definitely provide it for you with a custom print! Where you'd like the QR code placed?

Any particular model you like most?  https://AGORA.ftp.sh/tag/t-shirt/
