Engineered to be fast

Swapping details with somebody you have just met should not involve waiting. Umbel card pages run on global infrastructure and open in a fraction of a second, anywhere, on any phone. Google's own measure scores Umbel cards 100% for performance.
Umbel is meant to be the hassle free way to swap details when you meet someone. The one thing that can spoil that is the wait while your card loads on their phone, so we treat that wait as the problem to solve. Umbel is built to be fast.
Engineered to just work
Card pages run on global infrastructure, so yours opens just as quickly for somebody standing in Cape Town, London or Dubai. There is nothing for them to install and nothing to sign up to. They point a camera at your code, or tap a tag, and it opens in the browser they already have.
And it is fast
Fast enough that Google's own measure gives a card page 100 out of 100 for performance. The report above is a real run of one. In practice it means your card is on their screen before either of you has looked up.
A seamless contact share
They scan, your card is there, they press Save contact and you are in their phone. No app, no waiting, no apologising for the signal. The conversation carries on while it happens, which is the whole point.
