In almost every episode of Quan Zhi Gao Shou, you see the players inserting what looks like an ID card into a card reader of some kind. However, it appears it's more of an account card than an ID card. As far as I can tell, it's a Smart Card of some kind. I'm guessing it's a physical token used for account security. I know this anime is based on a game, is it related to how the game is actually played?
- What is this card?
- Is it used for person/player identification, or just account authentication?
- Are card readers like this commonplace in Asia and/or China?
- Does this card control the account, or do you also have to use the account password?
- Are these account cards easily accessible, for example at the Asia-equivalent of Walmart? In episode 2 or 3, we see the store owner's friend specially request her to provide an account, possibly indicating that they are hard to come by.
