Nowadays, many vending machines are made with photocells or cameras, which can be programmed to recognize visual marks on different bills. For instance, many bill-accepting vending machines identify bills by first scanning them with an optical reader. Many vending machines also use a magnetic reader to detect a bill’s magnetic signature, ensuring that it is genuine, and identify its denomination.
A slot machine is able to tell if a bill is real or not because it contains ultraviolet scanners similar to those used by banks and grocery stores that can detect a bill’s authenticity. Most slot machines possess such scanners, but they search for novel designs, so old bills may be able to bypass them.
A coin-detecting vending machine can tell a dime from a quarter, or a $10 bill from a dollar. Currency-detector vending machines have gotten more sophisticated in reading bills, starting in the 1990s.
TL;DR (Too Long; Does Not Read) Vending machines measure the coin’s size and metal to tell whether it is a dime, nickel, quarter, or quarter, which is an attempt to fool the machine. When you insert the coin into a slot, the machine uses a light sensor to sense the size, and an electromagnetic sensor to gauge the type of metal.
Scanner Variability Across Vending Machines
Some vending machines use ultraviolet scanners to measure the glare of a piece of paper to confirm that it is genuine. Bill acceptance machines read the bill to confirm its authenticity and record the dollar value using optical and magnetic sensors. The Bill Acceptor takes a bill, scans it for authenticity, and sends a corresponding I/O signal to its output connector for recording transactions. The high-tech bill acceptor is located in a counting room, where cashiers carefully deposit bills into a machine from a hopper.
Other machines in the classroom feature devices that measure bills to ensure that they are the exact size. Florence added that if the bills are found at a counting station, the guards may point the surveillance cameras at a machine where bogus cash is being collected. Fortunately for the vending machine manufacturers, real cash has safety features they can use to confirm real cash has been entered. Bill-validators in arcades are not designed to detect counterfeit bills; if they were, real currency, which could have been crushed, would be rejected, said one gambling source, who asked not to be identified.
That is why it is understandable slots could be targeted by casino cheats looking to rack up a bigger casino payout. Modern Slots machines and their Bill Acceptors are designed with sophisticated anti-cheating and anti-counterfeiting measures, making them very hard to defraud. Modern slot machines are controlled with EPROM computer chips, and at major casinos, coin acceptors have been made obsolete in favor of bill acceptors.
Winning Patterns Are Heavily Regulated
The winning patterns of the slot machines–the amounts that they pay out, and the frequency with which those payments occur–are carefully selected to produce a specific proportion of the money paid out to the house (the slot machines operator) while returning the remainder to the player throughout a game. It is possible to calculate that, for a long enough time, say 1,000,000 spins, a particular slot machine would return on average $950,000 to its players, who inserted $1,000,000 into it over that period.
Cashing out and inserting fresh bills will alter the time you are playing, but will change nothing about the way the machine pays. Even if a particular machine has been paying out all day, that is not an indication that it is going to keep paying tonight. The machine has no memory, at least of bonuses or large wins, or of who was paid.
Many players still believe a teller or some other person on the floor, standing in one place all day, could tell them what machines were hot — in other words, what machines were going to pay out. For all that has been written about how the modern slot machine works, there is still the common belief among players that those questions can be answered: that an attendant can give you the hot tip about a machine that is about to hit; that certain external signs that are visible on the slots games may indicate a machine is nearing a jackpot.
By playing a particular set of bets and games, players could confound a machine and cause it to malfunction, paying the jackpot.
Innovative Systems Around the Web

To cheat on the slots using magnets, You can spin the wheels, then use a powerful magnet outside of the machine to stop the wheels from spinning as soon as you see the winning combo.
Another outdated way of cheating on slots was using a light source to muddy the optical sensors used to count coins when it was time for a payoff. His light rod effectively blinded the optical sensor in slot machines, so they could not figure out how many coins had been put in the machine, and therefore could not figure out when or how much to pay out.
The coin bin is a small device wrapped around a piece of paper that tricked a slot machine into thinking it was accepting a $100 bill when it was only accepting the modest $1 bill. A string is attached to the coin, the coin is sent down the machine until it starts the game, then the player uses the string to pull the coin up again.
