Everything is weird in the US so can't tell how different it would be, but in Chile you can get a handheld personal car reader [1][2] for around ~25USD to 50USD, even if they needed something more specialized I really can't see them becoming prohibitively expensive, even the matching POS from the same company is just like 400USD[3] [1]https://sumupchile.com/products/lector-air?variant=39994977910833 https://sumupchile.com/products/lector-air?variant=399949779...
