Bump continues to be one of my favorite YC startups. They have a killer team, and incredibly novel technology that allows their software to easily work across platforms and that is years ahead of where NFC is.

I'm excited also for their continued integration with storefronts and other physical locations.

I dream of a time when all I need to carry is one device and no wallet -- Bumping to pay at the local grocer would be amazing. As it is, bumping to pay with PayPal is still great, but all I see for Bump is amazing potential.
