I. What is a security protection card (referred to as "密保卡")?

A security protection card is a card printed with an 8x10 random number matrix. Players can obtain a security protection card by purchasing a QQ card with password protection functionality. Using the security protection card, one can guard against Trojan horses and other account theft methods such as spying or intercepting user input passwords, to a certain extent.
