One thing PayPal is good at is bringing things to the masses. I recently worked at a small (3 person) real estate office and it was amazing just how empowered they were because of PayPal. They were able to use receipts, handle payments internationally, and much more all thanks to PayPal.
I'm extremely excited for this. While Square and others have made progress, PayPal is a household name and it can make waves like many others can't.
