At my EPU and transfer, my bracelet was handed to me and they asked me to check if the details were correct, and that's it! Mind you, when we were trying for Charlie, everyone at the clinic knew me by name, so it would have been unlikely that they would have mistaken someone else for me. But it was when I went back after having Charlie and, with all the new staff, no one knew me but didn't check that I was me anyway.
