Hi,
This is very helpful, great job and many thanks indeed.
Suggestion: when the site owner try to make a purchase with the client’s bank card, before the transaction is complete, it would be great if the cardholder could receive an email (automated) showing the details + total amount + approve and decline button, so that way our client can have peace of mind that we can not make any purchase unless they approve it.
I hope you find this helpful.
Kind regards,
Alistair
Thanks a lot Alistair! And thank you for the feedback, we are trying to make the process feel as secure as possible for the client, this suggestion is great and will be reviewed with the team.
Best,
Liron.
