What is a bill acceptor?
A bill acceptor (also called a bill validator or note acceptor) is the part of your gaming machine that reads and accepts cash from players.
It verifies paper currency and communicates with your machine to process credits. A quality acceptor ensures fast transactions, fewer rejections, and smooth customer experience.
How does a bill acceptor work?
Here’s a step-by-step breakdown:
- Insertion
A player inserts a bill into the slot. - Scanning
Optical sensors scan the bill’s size, ink pattern, magnetic signature, and security markers. - Validation
The system checks if the bill is authentic and acceptable.
If valid, it proceeds; if not, it returns the bill. - Stacking
Accepted bills are moved into a secure cash box for collection. - Credit Communication
The validator sends a signal to the machine, adding credit to the player’s balance.
💡 This entire process happens in under 2 seconds in high-performance models.
