We had to jump through hoops with Nationwide to get the kids' accounts transferred to them when they were adults.
As for the NHS app, I can't remember exactly what I needed to do, but I had to go into the Dr's surgery with some paperwork. In exchange, they gave me some codes with which I could set myself up on the app. This enables me to see all my test results, order prescription meds and make appointments.
As for people ringing you asking for information, my bank did this. My memory is awful, so I'm copying this from another forum where I posted it:
Somebody rang me saying they were from my bank and could I confirm who I was starting with my DoB?
I told them you gotta be having a larf. They were most taken aback. I asked if the call was being recorded and they said yes. Great I replied, this will be a good one for training! How the heck do I know who you are? You ring me out of the blue, I'm not expecting your call and then you ask for personal details? I know it's your number in my display, but scammers can spoof any number these days.
I asked her to tell me which day I was born on. She told me she couldn't divulge that information due to regulations blah, blah...
I said don't be silly, I'm not asking you to tell me my DoB, I'm just asking you to tell me the day of the week on which I was born.
That way, I will know that either you are a scammer that has got lucky or you are genuine and have my DoB on your file and you have looked up my day of birth on the internet.
She went away to talk to a manager and came back and said that yes, she could do that.
I'm thinking of other questions I could ask too.
I took it up with the bank afterwards and made an official complaint.
Surely it's better just to ring and say "It's xxx bank here. Can you ring us using the number you normally contact us on?".
This way, the customer knows they are talking to genuine bank staff.
