Capital One’s shopping assistant Eno can now dole out virtual card numbers in the browser — Techcrunch — “Capital One’s card numbers let you pay without needing to use (or even locate) your credit card account information, once the extension is set up and configured. The extension instantly creates virtual card numbers when you go to a site’s checkout page… The Eno extension will also auto-fill your payment information on the checkout page, and reappear when you return to the same site.”
