This article is for you if you want to know how your vouchers are handled.
Here is the progress of the path that your vouchers take:
You can send us your vouchers as you wish with or without password. For information, sending by Google Docs is secure because the data is encrypted by Google.
The vouchers are then stored with us on Amazon S3 and are encrypted by Amazon.
Your vouchers are then sent to our payment partner Treezor for validation in HTTPS. We automatically retrieve them from Amazon S3 and then send them.
