Arcade machines have evolved from standalone cabinets to interconnected nodes in a network. This connectivity allows operators to manage games, process payments, and track player data efficiently. Several protocols have been developed for this purpose.

One of the most fundamental standards is JAMMA (Japan Amusement Machinery Manufacturers Association). While primarily a hardware standard for wiring within a single cabinet, it laid the groundwork for simple communication. Modern networking protocols often build upon or interface with these foundational connections.

For contemporary arcades, a leading protocol is ArcadeNet, developed by Adrenaline Amusements. This system enables features like cashless play using RFID cards, centralized prize redemption, and remote game management. Operators can monitor earnings and player activity across their entire venue from a single computer.

In the realm of video arcades, Sega's ALLS (Amusement Linkage Live System) is prominent. It networks Sega's latest arcade cabinets, allowing for competitive online play between players on different machines, nationwide leaderboards, and downloadable content updates to keep games fresh.

For the casino and redemption game sector, protocols like IGT's SAS (Slot Accounting System) are dominant. SAS is a robust and secure protocol that facilitates cashless wagering, player tracking through loyalty cards, and crucial regulatory compliance and auditing functions for casino floors.

In summary, while JAMMA provides the basic electrical backbone, modern networking relies on specialized protocols like ArcadeNet for family entertainment centers, Sega ALLS for connected video gaming, and IGT SAS for the casino industry, each tailored to specific operational needs.
