# Autofill cards and identities

> Locker can autofill card information and personal identity details to speed up your online payments and account registrations.

Locker can autofill card information and personal identity details to speed up your online payments and account registrations.

We use a Machine Learning autofill engine to detect different field types on the websites you visit and fill in the most appropriate information with high accuracy.

<Note>
  The Card and Identity autofill service currently only works on browsers.
