> Who are these businesses? Seriously, stop issuing cards without chips and send new card readers to theses businesses. End of story. Alternatively - do what Monzo does in the UK and issue cards with a magnetic stripe that is disabled in the backend by default. If you try to use the magnetic stripe, it sends you an alert that says "Someone (possibly you) tried to pay using the magnetic stripe. Do you want to allow the magnetic stripe for the next hour?" Then if you travel to a country that relies on magnetic stripe, similarly it sends you a message saying "You have travelled to X - sometimes you may need to enable the magnetic stripe in order to use an ATM. Do you want to temporarily enable the magnetic stripe?"
