is nothing more important to the profitability of a gaming

X-Mark Tokens and Xeptors
Gets A Clean Shave..... Keep Him Out Of Your Slots !!
Articles On Coin Shaving
hand side quarter has had about 0.040" shaved off its diameter in
order to trick the machine into ejecting coins from the hopper without
counting them. Most casinos have fallen victim to this scheme for
emptying the slot's hopper without know it was happening. The change
in coin diameter is small enough to escape casual visual detection.
Inductive comparison type coin acceptors cannot distinguish such
slight coin diameter changes and can be tricked into accepting shaved
coins by "slamming" them. Shaved coins go in for credit and come out
The best way to stop this is to prevent shaved coins from entering
your machines in the first place. IDX Xeptors have advanced diameter
detection optics that precisely measures the diameter of each coin,
typically to within +/- 0.005". In order to accept the coin, it must
fall within a +/- 0.015" window of the average diameter of the sample
set of coins used in the training session to learn this coin type. The
result is that if George or any other of your tokens gets a shave, IDX
Xeptors will cleanly and reliably reject them, thus preventing your
profits from being shaved as well.
Get The Lead
Out..... Don't Participate In Their Slug-Fest !!
A fist full of
lead slugs is neither a welcome sight for honest customers nor for
casino management. In spite of the well known nearly identical
inductive alloy signature between common lead and nickel-silver alloy
tokens, many casino properties continue to use this alloy (see upper
left token) leaving their machines open to garage-shop counterfeiters
who produced lead slugs as pictured in the right hand column and found
in the hoppers of slot machines throughout the industry.
Since it is impossible to make something perfectly counterfeit
proof, the object then is to raise the level of difficulty and expense
of counterfeiting high enough to eliminate the vast majority of
would-be counterfeiters. Optically encoded X-Mark Tokens minted by
Osborne Coinage and state-of-the-art Xeptors produced by IDX jointly
offer a number of solutions to the "lead slug problem". Now you do
have the tools to put an end to their Slug-Fest!
- Security alloys, as
depicted by the lower left token, are available form Osborne Coinage
with inductive signatures much different from lead. The unusually
low melting temperature of lead and the unfortunate match of its
inductive signature to common nickel-silver alloy tokens resulted in
wide spread counterfeiting. By utilizing these security alloys, the
simple garage-shop counterfeiting process of melting lead and
pouring it into plaster molds is eliminated. Melting and molding
other much higher temperature alloys is a much more difficult task
requiring special equipment and materials not commonly available.
- Multi-alloy tokens
can be minted as shown in the X-Mark Tokens page. This construction
complexity and the need to match two alloys substantially increases
the difficulty of counterfeiting this type of token. Unlike all of
the competitive units sporting quite large inductive sense coils,
the IDX Xeptors are purposely designed with a small diameter
inductive sense coil and a centered coin path making them the only
coin acceptors capable of distinctly reading both the alloy on the
edge of the coin and in the center of the coin.
tokens have a machine readable optical mark minted into the
surface of the token in a circular band near its periphery. The
reflective requirements and angular geometry of the
X-Mark tokens prevents them from being
easily duplicated in a garage-shop by pressing a real X-Mark token
into soft metal, pouring lead into crude molds, or by cutting
surface grooves with a lathe.
Unwanted Shadow Coins. Figure 1below show a typical upper
and lower limit of acceptance about a normal distribution of
readings for a group of coins, presumably identical. All readings,
however, are not identical because of slight variations in alloy,
diameter, or thickness of coins. Due to the thousands of different
coins minted in the world (in addition to all of the slugs) there
will occasionally be cases when an unwanted coin "shadows" the valid
coin as shown in Figure 2. Without further measures, this unwanted
shadow coin would often be accepted as the valid coin. The IDX
Xeptors have a solution for this problem. You can specifically
program in this shadow coin as an "unwanted coin". When a coin falls
into a category of both the shadow coin and the valid coin, the
Xeptors will compute the sum of errors for the coin's four measured
parameters relative to both the shadow coin parameters and the valid
coin parameters. The closest one wins. The result is you retain high
acceptance of the valid coin and get rejection of the unwanted
shadow coin. This works well for imperfect slugs as well as foreign
currency or tokens that are nearly, but not quite identical.
Headaches? ... It's Like Casinos Are Everywhere !!
Cost & Legal Considerations
of the four tokens on the right have the same diameter, the same
thickness, and the same alloy. However, they each have a different
optical code minted in them that enable IDX Xeptors to distinguish
these as four distinct tokens. For example, the lower right token is
1.465" in diameter, 0.10" thick, the alloy is nickel-silver, and the
minted X-Mark code is 60-120. An Xeptor programmed for only this coin
will reject the other three. Furthermore, it will reject tokens with
the following differences:
- A change to another of many X-Mark codes.
- A change in metal alloy; edge, center, or both.
- A change in diameter or thickness.
So, when you use X-Mark encoded
tokens and IDX Xeptors you can
stop paying for all of that back room sorting activity and forget
about being stuck with crossplay tokens from casinos you never heard
of. When you are ready to stop the crossplay, we will be ready to help
you with encoded tokens.
So... Do You Know Who Programmed It For That Coin?
X-Key is an electronic security key
for use with IDX Xeptors. After a first use of the X-Key with an
Xeptor, the Xeptor becomes secured from further programming unless the
X-Key is plugged in. The X-Key keeps a record of each Xeptor that it
was connected to and the Xeptor keeps a record of the time and date
stamp, and personnel ID of the person who enabled the X-Key. The X-Key
is enabled and disabled through X-Tracker,
a Windows based software utility for managing and tracking X-Key
activity. Data from all X-Tracker transactions is stored in an
encrypted redundant file system on the PC.
