Setting up the tap-to-pay feature is quick and easy, according to PayPal, with initial setup being free of charge. While the rollout for all Venmo businesses is scheduled to take place over the next few months, interested merchants can sign up for early access. The service is already available to all PayPal Zettle users in the US. Additionally, PayPal has announced that Tap to Pay on iPhone is now accessible to certain American users, with availability expected to expand to all users in the near future.
