Canadian here: we don't reprogram cash registers. They tell the exact amount and then we're charged either the exact amount (via card) or a rounded-off amount (if paying cash).
FWIW, 86% of "total payment volume" in Canada was digital, and 53% of transactions were contactless. If that's not the case in the US, it may be more of an adjustment.
