Qr codes?? Good idea or not??

So I was thinking about getting one of these custom qr keychains and linking it to my link tree, so people would be able to follow me wherever they want! But I feel like it would be a quick easy think having them scan it. I've seen girls do stuff similar where they will put them on their magnets they pass out when you tip them on stage, so I was thinking this would be easier when going around person to person! What are your girls thoughts on this??
