I've read that whole article and I'm still no clearer as to what they actually do. I understand Amazon's "one-click" technology, as Amazon already has all my address and payment details saved.

Am I therefore expected to create an account with Bolt so they can store my details and offer a "one-click" experience on downstream e-comm sites? How is this different to what PayPal offer, especially given PayPal is ubiquitous?
