The infamous Bat-Credit Card was a credit card Batman used when he needed monetary transactions.
- The "Bat-Credit Card" is often seen as the worst element of Batman & Robin. The internet celebrity Nostalgia Critic (Doug Walker) did a review on Batman & Robin, and the mere sight of the "Bat-Credit Card" sent his character into a homicidal rant. Mentions of it in later episodes caused the Critic to begin firing his gun around wildly. It has since become one of the most famous gags performed by the Nostalgia Critic, with him reacting violently every time a reference is made to it.
- Walker later explained that the reason for disliking the Bat-Credit Card is because of the fact that Batman, as a superhero, needs to keep his identity hidden. In order to get a credit card, he would have to give away information, such as his name and Social Security number, thus revealing his identity.
- Linkara (Lewis Lovhaug) however, during his review of the comic book adaptation (in which the Critic cameos in) argues that because Batman is wealthy, he is able to get away with the credit card by funneling his money through shell companies and false identities. This revelation even shocks the Critic who is then told to get into a corner thus ending the meme altogether
- The cards expiry date is "Forever" linking to the films predecessor's title: Batman Forever.
