Link LetsExchange
LetsExchange is a website, so the ERA shows a single instruction and a lower-density QR code that a webcam can read.

On the wallet screen, tap the settings icon (sliders) > Link. See Open the Link menu.

ERA: Wallet settings. On the wallet list, swipe up to the third page and tap LetsExchange.

ERA: Wallet app list. On CONNECT LetsExchange, tap SHOW QR. The single step reads "Go to letsexchange.io and follow the instructions there".

ERA: Connect LetsExchange. QR FOR LINK appears. Leave it on screen.

ERA: QR for link.
Part 2: On letsexchange.io
