Our customers are only required to bring the redemption letter to our shops to exchange for their gifts. If they cannot provide the letter,they have to fill in and sign the required application form to identify themselves. Then our staff will only check their identity cards without photostat. However it may violate the law of privacy of our customers if we found that our staff have attached the photo copies of their identity cards to the application forms by our audits.
