 Introduction  
General Statement  
The Purpose of this Technical Standard is as follows:  
a) To eliminate subjective criteria in analyzing and certifying Card Shufflers and Dealer Shoes.  
b) To establish the minimum integrity  standards for card shufflers and card shoes that are 
technology neutral.  
c) To only test those criteria that impact the credibility and integrity of Card Shufflers and Dealer 
Shoes from both the revenue collection and player’s play point of view.  
d) To create a  standard that shall ensure that the card shufflers and dealer shoes are fair, 
secure, and able to be audited and operated correctly.  
e) To distinguish between local public policy and laboratory criteria.   
f) To recognize that non -gaming testing (such as electr ical testing) should not be incorporated 
into this standard but left to appropriate test laboratories that specialize in that type of testing.  
g) Except where specifically identified in the standard, testing is not directed at health or safety 
matters.  Thes e matters are the responsibility of the manufacturer, purchaser, and operator of 
the equipment.  
h) To construct a standard that can be easily changed or modified to allow for new technology.  
i) To construct a standard that does not specify any particular method or algorithm.  The intent is 
to allow a wide range of methods to be used to conform to the standards, while at the same 
time, to encourage new methods to be developed.  
No Limitation of Technology.   
One should be cautioned that this document should not be read in such a way that limits the use of future 
technology.  The document should not be interpreted that if the technology is not mentioned, then it is not
