Integration with "PayPal Here" (accept credit card payments on the go).
Integrate mobile app for administrators with PayPal Here in order to accept credit card payments.
Please vote to this suggestion if you prefer using PayPal Here instead of Square Register.

If you offered integration with Stripe that would be even better as that is what we use for the website side. We still have a PayPal account so that is why this would be the alternative choice as that is what we use for our cash register.
