PJ issues warning about 'contactless': paying in 'tap and go' mode can be expensive
The Judicial Police (PJ) warns consumers to always verify the amount on the terminal before paying with contactless technology. While transactions of 50 euros or less do not require a PIN, criminals are exploiting this 'tap and go' convenience to charge unauthorized amounts. The Bank of Portugal notes that PINs may be randomly requested for security, and are mandatory for transactions exceeding the contactless limit.
