American Express plans to roll out a new feature in the American Express mobile app allowing cardholders of eligible cards (Centurion/Platinum) to access Centurion lounges without the physical card. American Express plans to offer this starting sometime in June and it seems like this is a possibility due to the LoungeBuddy acquisition. When checking in using the app you’ll have 30 minutes from the mobile check in to actually access the lounge using the QR code generated.
Personally I don’t think that American Express has introduced this to help people who forget their physical card. I suspect it’s being done to help manage crowds and American Express will further restrict access, either by limiting the amount of guaranteed entries you get or shortening the window the lounge is accessible for before your flight.
