What user facing aspects bug you the most?
I'd love: - Universal, near-instantaneous per transaction alerts. It helps stop fraud right away rather than after-the-fact. It also helps solve problems while they are fresh rather than trying to resolve a month-old+ issue. Some countries overseas do this almost universally. - On-restaurant-table credit card swipe rather than taking the card away and entering tip later. Many places overseas do this almost universall…
If they took the card away, how would you enter the card's PIN? That's why places outside the USA do the swipe on the table.
