neiman marcus gift card question

  1. I just bought a Neiman Marcus Gift Card on eBay. I was wondering if the CIN number is hidden/scratch-offable (like sephora)? The ebayer said he/she will email the code and sent the card. But if the code is hidden and will be exposed, I feel like I should request the code not be emailed. If the CIN # is viewable to all, I might as well get the code and spent asap.
