What is this close-up picture? (WotsThat: SD card contacts (macro))

SodaliteDrift · Accepted Answer

SD card contacts (macro). The tiny gold contacts on SD cards are actually arranged in a specific pattern that lets your device automatically detect what type of card it is just by checking which pins make electrical contact, meaning a camera can instantly tell the difference between an SD, SDHC, and SDXC card without any software trickery. Even wilder, those contacts are so precisely positioned that if you physically modify an older, slower SD card by covering one tiny pin with tape, you can fool modern devices into treating it like a faster SDHC card.
