MyIDapp

MyIDapp is great for keeping your ID up-to-date and sharing it safely and securely when you need to do so
The latest version also allows safe face-to-face document sharing - allows proof of address to be provided and copy of passport and / or driving licence. You can collect counter signatures on a retained copy. This is often needed for high-value agreements such as car leasing and other credit agreements
Also quickly proves your age for access to clubs and bars, buying drinks, or for buying age restricted goods
And you can securely show your passport or driving licence upon request
Someone challenging your age can even validate via a QR code without needing a copy of your ID. And you can zoom to your photo ID

MyID app also reminds you in advance of Passport expiry date and prompts you to renew. Similarly does the same for your driving licence - don't incur a fine or worse for the oversight!
