I've just checked what I said upthread about not needing to collect from the machine from the nominated station or indeed, be the correct person.
I have to go to a team meeting in Nottingham on Thursday. My line manager and I purchased tickets on-line today, and after I explained what I wanted to check, she gave me a print out of her confirmation e-mail containing the collection code.
She had nominated Five Ways Station as the collection point. I have just picked her tickets up from Bournville (wrong Station) using my debit card (wrong person and type of card).
This is very useful if you ever need to buy tickets for family members who live elsewhere. You just need to text them the collection code.
