Bill Acceptors - Serial vs. Pulse

When putting a machine together with a bill acceptor, you must decide whether you want a pulse or serial connection. 
But you might wonder: What’s the difference? Don’t they both work? Which is better? Why should I care? Let’s look at some differences between the two options.

 A pulse connection between the bill acceptor and the game board uses a pulse of electricity to communicate information (i.e., how many credits the customer has put into the machine). 
A serial connection between the bill acceptor and the game board uses a direct line between the bill acceptor and board allowing them to perform a “handshake” (e.g., a way to secure the transaction). 
Both forms of connection do work. However, the best option to use, when applicable, is serial. It automatically makes sure that the credit into the machine is accurately communicated with the board. In a pulse connection, this can be tampered with. As mentioned, serial is good when applicable. Not all boards support serial communication with the bill acceptor and must use a pulse connection.
In these cases, we strongly recommend that you install a “Shutoff Alarm Kit” to prevent the successful tampering of your machine. The Shutoff Alarm Kit will automatically shut down the machine in the event of an EMP attack on your machine. Thus, not allowing the criminal to scam you.

Security from being scammed is the goal in this decision. Choose serial when possible and utilize a shutoff alarm kit when using pulse.
