We tested a 12-second cashier script plus a QR on the receipt and lifted enrollments 18% over 4 weeks without slowing the line on a Square POS. What frontline-friendly tools or phrasing do you use to invite signups in a way that feels helpful to customers and keeps throughput steady?
But i like the QR idea! It’s like giving customers a treasure map — short and sweet but leads them to something valuable. Have you thought about offering a small incentive, like a discount on their next purchase, to sweeten the deal while they’re in line?
Have you tried offering instant rewards, like a discount on their current purchase? It can boost signups even more!

I love the idea of QR codes! It’s like a digital handshake. One thing I’ve seen work is a quick pitch about how signing up can save them money on future purchases, which keeps it focused on customer benefits.
