In order to enter a Pokemon Trading Card Game Online code in exchange for digital booster packs, decks or individual cards, log in to your account, click on the Shop tab, and then click on Redeem Code, which opens a field to type in the code. After the code has been entered correctly and submitted, you can claim the corresponding cards.
You can find codes in physical packs of cards that state on the packaging that a card with a digital code is contained within. You can also find codes online that are redeemable more than once after other users have shared them. These codes come from the iPad version of the game.
The online version of the Pokemon Trading Card Game began in 2011 and has since expanded from a browser-based game to the desktop and to the iPad. The original physical game originated in Japan in 1996 and was later brought to the United States in 1998. The game involves using cards featuring anime creatures to battle other card collectors. Each card and its corresponding character possess attributes and attacks that the card collector then uses to battle an opponent. Character cards require additional "energy" cards in order to perform attacks.
