Have you guys seen quickboardapp.com ?
Having a custom 1Password keyboard that users could quickly flip into to access parts of identities or memberships card numbers. Anything really I guess would be amazing.
Just imagine writing an email and you needed to send out your reward card number. You could flip to the 1Password keyboard, (which I guess would show a pin code screen at first) enter the pin, find the reward card, tap the number and it would auto paste it into the current new email.
