A fraud issue
I sent these to several of my close friends. So far, two of them told me that the cards do not work. I directly bought them from Amazon and never opened it. As many others reported, a large scale fraud is going on. You should not buy this for now, and Amazon should investigate the issue swiftly.<br /><br />Editted on 12/15/21: It turned out that the issue was caused by AWS Outage, and it was resolved automatically after a day.
