Will it stand up on its own?

Yes, it will! However, if I am being honest. I would not recommend this product. Very cheaply made. My first day using it on a business trip. The lock would not stay locked and kept popping open making travel very frustrating. The company sent replacement parts however, I only found myself to be even more frustrated trying to replace the broke part. Even the replacement parts are cheaply made. The only good thing about this bag is the presentation. It’s a beautiful bag just poorly made. Good luck!

Does the top of the briefcase stay wide open on it's own for easy access ?

Yes, the top of the briefcase stay wide open on it's own for easy access.

Yes. A small lock just minor deterrent

Is this passport cover rfid protected? the description eludes that it may be rfid, but no where does the description actually states this is rfid

I can not say 100% but without any mention of it - I assumed it was not RFID protected - so on my trip I bought some separate protectors - however that made the passport too big to fit in (tight fit) so I tore apart 2 of the foil bags and created a school book wrap style protector and it fit fine...
