Yes, very.  BOPP is committed to safety and security and is regulated by the UK Financial Conduct Authority.

At no point are anyone's bank login information exposed meaning that all our users are always in complete control of their bank accounts. One of the big benefits of BOPP is that there is no risk of card fraud (where a malicious third-party steals your card data and spends money from your account), BOPP simply and securely transfers a payment request to the payer for the payer to safely pay from within the security of the payer's own bank application.
