I'd like to suggest to have a notification feature in the app. Some items, like credit cards, debit cards, driver's license, passport, and possibly many others, have expiration dates. You could optionally mark items like these and the app will notify you if the expiry date is approaching (or reached).
Some might say, ok, but credit card companies will send you a new card anyway. Well, true, but, you prolly have an internet service and store your account info in 1PW. And as we know, some services are corrupt (eg internet companies) and once you sign up for a 1 year service you need to call them to extend the service for another year in order to get a discount, else they will switch you to month-to-month which is obviously more expensive. This is another reason to mark some items to notify you.
