In Store Check Out Fraud?

[Makstarn]

If I enable in-store checkout on my account, is it true all that is needed is to enter my phone number at the point of sale?

If so, doesn't that mean that someone other than me, who knows I use Paypal and has my phone number, can make purchases using my Paypal account?

I am hoping to be informed there is a bit more security involved than simple possession of my phone number.

There is also a pin number that needs to be used.  So there is more than just your phone number.
