I went through a round of this with my bank a couple of years ago. They would reissue a card that would be compromised in days and the cycle would go around. It was an internal security problem for them that eventually got sorted out. I remember one card was cloned and bought several dozen monthly transit passes in Boston (contactless purchase) before it was caught. I live in Western Canada. So yes I carry cash. A lot of younger retailers don’t even accept it. They just have that square tap system tied to their phones.
I am really having trouble believing it went down like that. Analyzing one specific runners routine is more like stalking than anything. Especially given that there is a wealth of material on high mileage plans (Pfiitzinger anyone?).
