Signed up!

I signed up and finally got my card in the mail. I have questions and some of the videos I’ve watched didn’t go into details.

1. What’s the difference in using the app or the card to pay for items?

2. Does the app tell you the where abouts of the delivery address? I do uber eats and it gives cross streets so I know where I’m going before I accept the order.

There’s high crime areas like 5-6 miles from me but 5-6 miles in another direction however, there is 1 million dollar homes, wider streets, street or driveway parking and no real worry about getting robbed or double parking. Thanks in advance
