Dear Khun Direk,
We are surprise to hear that this will be for passport instead of passbook which you informed yesterday. In this case the security aspect about such application for the supply of printer will be critical, it is necessary for our understanding about the end-user as this information will be required by our principal. Are you able to inform the end-user and the passport is for which country?
How about the making of passport booklet itself, will you be helping them with this? What is the quantity? Maybe we can also help you to check? I think currently the Thai passport is produced by Chanwanich, maybe it will be supplied by them as well?
We hope you understand that due to the nature of this application, the security level will be much higher and this is the reason that we are asking for those information.
Thanks and regards
YC Lee
