How to connect the WisePad 3 as a payment device through the WriteUpp Pay app (Stripe Unified)
The WriteUpp Pay app allows you to connect a WisePad 3 card reader to take in-person card payments using Stripe Unified.
A benefit of connecting a WisePad 3 reader is that it allows the customer to insert their card and enter their PIN to complete the payment, which is useful for transactions over the contactless limit.
Before pairing the WisePad 3, you must first log in to the WriteUpp Pay app on a compatible mobile (or tablet) device. Once logged in, you can then connect the WisePad 3 via Bluetooth and choose it as your preferred payment method.
