Arcade machines have evolved significantly in supporting player avatars and customization, moving beyond simple high-score initials. Modern arcade cabinets often integrate with player card systems, such as Bandai Namco's Banapassport or Sega's Aime cards, which store user profiles directly on networked servers. When players swipe their card, the machine accesses their saved avatar, character unlocks, control preferences, and cosmetic items from cloud-based data. This allows for persistent customization across multiple arcade locations.

Many fighting games and rhythm games utilize avatar systems where players can select character skins, accessories, and color schemes that display during gameplay. Hardware features like card readers, USB ports, and online connectivity enable these personalized experiences. Some arcades even use camera systems to capture player images for custom avatars. The technology maintains fast access times while storing complex profile data remotely, ensuring personalized gaming experiences remain consistent wherever players use their cards. This approach has become standard in Japanese arcades and is increasingly adopted globally.
