Hi Dev TEAM LBRP,
It's possible, but you would have to write that integration yourself. PointShop integration and a marketplace are not included in Card Engine. Instead you would add your own item to PointShop and give the card or booster pack to players who buy that item (see the CardEngine.Collection.AddCard function in the documentation or the section at the bottom of the creating a collectible card).
Be sure to check out the integration examples in the documentation before purchasing, so you can check if Card Engine fits your needs as is. You can find examples there that show how in DarkRP or Helix the cards and booster packs can be made into items that can be dropped and picked up (trading that way).
And thanks for the offer to translate it!
