A Tokiwadai Middle School student being tested with a Zener card.
Zener Cards (ゼナー・カード Zenā Kādo?), also known as ESP Cards, are cards used in System Scans, most specifically, clairvoyance.
Appearance[]
Zener Cards
There are five different Zener cards: a hollow circle (one curve), a Greek cross (two lines), three vertical wavy lines (or "waves"), a hollow square (four lines), and a hollow five-pointed star. There are 25 cards in a pack, five of each design.[1]
Principles[]
The esper being tested must be able to determine what the contents of the card are correctly.[2]
Background[]
Perceptual psychologist Karl Zener designed the cards in the early 1930s for experiments conducted with his colleague, parapsychologist J. B. Rhine.
In Toaru Majutsu no Index, the card's material was changed from vinyl to ABS resin, which was instituted by the United States of America in 1992 due to a trick that the fingerprints on the card made it possible to determine the card's contents.[3]
