Both PayPal and Square have mobile card reader devices that work with tablets and smartphones. If you already have a PayPal account, you just need to add PayPal Here to accept physical cards. Request a free PayPal Here card reader, add the PayPal Here service to your existing Pay Pal business account and download the PayPal Here app to your tablet or smartphone. That’s probably the simplest way for you to accept credit cards since you already are on board with PayPal.
I hope this helps, Good luck! Krista
