There are at the time of Wild Force only a few Org on Earth at a time,and it's implied to have been that way for five thousand years. Surely not enough to develop a credit system. Definitely not organized enough to have cards with his own face on it.
Whether or not Jindrax is even successful at using the card is unknown,as we never actually see him use the card. He presents it to the cashier and then later he has the fishing rod.
Also strange,when the cashier asks him to pay for the rod,Jindrax pats his legs where pockets would be if he were wearing conventional pants. Why would he think he had money,as he is never shown earning any,unless he still has some from his job at the animal testing lab,where he was in human disguise. It's possible he's picked up subconscious habits from being human for so long.
And now I've reached my daily limit of nerd and risk overheating.
