cdk is cdkey
CDKEY refers to the serial code required for software registration. According to the literal meaning, it can be understood that CD is a disc, and KEY means a key. The translation is "the key to open the disc". The professional term is called the registration code, which is actually the registration code and key of the software; but this password is different from the ordinary password. The only thing is that it can only be input by reading a disc and cannot be input from the keyboard. Even if others know it, it will not work. Generally, online banking needs to use it to ensure the security of customer information. The password or serial number of the software installed on the CD is CDKEY. For example, the system installation CD requires you to enter the number in a row of long boxes when installing the system.
Many online games now have CDKEY. After registering a game account and binding CDKEY, you can generally receive a lot of novice rewards. At the same time, these rewards may not be in the game. They are a means for game companies to promote games. .
CDKey alone cannot complete account registration. You also need a monthly card or credit card to activate CDKey. Because game companies charge a certain monthly game fee every month. Activating with a monthly card or credit card is the payment method for players' monthly fees. Therefore CDKey has only one function: register an account. The monthly card or credit card has two functions: one is used to activate CDKey, and the other is used to renew the existing game account.
