Ah yes! My bad. I typed that then thought “Actually I see them in a lot of places”. I meant to go back and edit but in the excitement of it all, I clean forgot.
My apologies. You are quite right.
The only places I’ve ever encountered anybody using them is at those type of gyms that force you to log into machines and track your progress on your phone and on a central database.
Not the sort of gym I’m interested in.
Oh and I think I’ve checked onto flights and into venues with them...
