as opposed to just entering the number (they thought they had memorized).
On my last cruise with RCI, my dining room waitress appeared to do this. I was ready to give her my SeaPass card the second night, and she said she had my number memorized. However, I had to get a new SeaPass that second night after dinner, because I stupidly locked myself out of my room. I went back to my room briefly after dinner and before the show, and forgot to put my passport holder, which had my SeaPass in it, back in my pocket. I don't know what my waitress did that third night when I had a new SeaPass and my folio number changed.
