Introduction to VCCS
This is Coca-Cola’s standard interface used in Japan and other Asian Pacific Rim countries. It’s like a connection that helps Coca-Cola machines accept coins, cashless payments, and bills. There’s one plug that provides power and communication signals.
VCCS is a protocol communication standard used widely in Japan’s vending machine industry. Similar to MDB, the communication standard helps establish a common protocol to inter-link numerous devices used in a vending system. It is a very common protocol used on vending machines made in Japan.
Japan is famous for her wide range of vending machines on the street. You can easily find machines within a 100m radius in Japan’s cities.
Besides VCCS, there are also many other standards used in the vending machine industry across the world.
- MDB (Multi-Drop Bus) vending protocol.
- DEX (Data Exchange)
- CCTalk (Coin Communication Protocol)
- MEI Protocol A (Executive Protocol)
- BDV (BDV001)
- EVA-DTS
- MEI Micromech
- Simplex III/L+
- Simplex0
- Simple Pulse from coin/notes acceptor
Protocol Converter
There are so many vending protocols and they can be overwhelming for integration work. This is especially true with VCCS protocol, there is hardly any documentation available from the internet. A converter is going to make integration work simpler.
To make things similar, there are also converters on the market that help convert vending machine protocol. It is like a translator that helps machines talking in various languages to understand each other and work together in harmony.
