关于斯里兰卡ETA的问题

申请了ETA，然后立马收到一封确认申请邮件，过了一个多小时，收到另一封电邮。内容如下：

ETA APPROVAL NOTICE.We are pleased to inform you that your application for ETA has been approved.ETA Number: *************Name: ***********Passport Number: ************Nationality: CHINA (CHN)Purpose of Travel: Tourist - Sightseeing, holidaying (You are NOT permitted to use this ETA for any other purpose)Entry Type: DoubleValidity of ETA (DD/MM/YYYY): This ETA must be utilized before 13/06/2014............This is a computer generated notice and carries no signature or seal.
难道这个就是ETA吗？把这页打印出来就可以了吗？
