Expedition also introduced an updated card design, which included numerous changes. Firstly, the cards incorporate the Dot Code technology for use with the Nintendo [[e-Reader]]. By using the device, players were able to view Pokédex data about the Pokémon, play a minigame, play various tunes in a [[Construction: Melody Box|Melody Box]], or activate a [[List of TCG cards with hidden attacks|special attack]] for that Pokémon. However, these special attacks were not legal for use in tournament play as few competitors used e-Readers. As well as this, in events by [[Pokémon Organized Play]], electronic devices such as the e-Reader are not allowed on the table. Due to this feature, the left and bottom borders had been increased in size. The card also lacked the Pokémon's species, length, weight, Pokédex entries, and level (Non Holofoil Rare prints contained them), which were stored in the dot code. The illustrator and copyright information swapped position, and the set symbol is moved to the right side of the card number and rarity. Each card has an unique ID number in order for the e-Reader to distinguish each card with the same name in a way other than by level, which is located below the artwork.
Expedition once again featured Reverse
Holofoil cards, but the design was changed to a plain "refractor" Holographic effect. One problem brought to Wizard's attention was that both the Holofoil and Non Holofoil Rare cards would have had identical Reverse Holofoil counterparts. Wizards rectified this in Aquapolis and Skyridge by numbering the Holofoil cards differently and only producing a Reverse Holofoil prints of Non Holo Rare cards.
Because of the extra licensing fees Wizards had to pay to use the Dot Code technology, the booster pack size was reduced from 11 to 9. Each booster pack contained 5 Common cards, 2 Uncommon cards, 1 Reverse Holofoil card, and 1 Rare or Rare Holo card.
