In France, the contactless card limit rose from €30 to €50 on 11 May 2020, during the pandemic. Above that, you must enter your PIN. Even below the cap, the EU's payment services rules (PSD2) require a PIN after a certain number of contactless payments: five in a row or €150 in total, depending on the bank. It isn't the terminal glitching: it's a safeguard in case your card is stolen.
