What is Tap to Pay on Square?


Tap to Pay on Square lets merchants accept in-person contactless payments using a supported mobile device and their connected Square account. It expands the payment methods available through Chat To Clients CRM mobile POS while allowing businesses to continue using existing Square options when another payment method better fits the transaction.


Tap to Pay on Square works through the Chat To Clients CRM or Chat To Clients CRM mobile POS and integrates with the Square account connected to the selected sub-account. For the iPhone workflow, the phone itself acts as the payment acceptance device, so a separate Square Reader is not required. Customers can present supported contactless credit or debit cards or compatible digital wallets such as Apple Pay and Google Pay.

Key Benefits of Tap to Pay on Square


Tap to Pay gives businesses another flexible way to collect payments during face-to-face transactions. It can reduce reliance on additional payment hardware while keeping payment collection inside the existing Chat To Clients CRM POS workflow.


Prerequisites for Square Tap to Pay
