The WR99 is intended for stored value applications
where all account information is securely and redundantly stored
on an ISO 15693 RFID (radio frequency identification) tag called a
Wicket. Stored value technology eliminates the need for networks
and servers while still providing the utility of an account
balance, a bonus balance, a loyalty point balance, and an optional
customer PIN. The WR99 Wicket Reader utilizes its emitted RF field
to both power and communicate with the chip/antenna of the Wicket.
The WR99 differs from the WR88 non-gaming
Wicket Reader in that protocol security is higher and the
responsibility for maintaining records of incomplete transactions
involving player credit is borne by the gaming equipment.
The WR99 incorporates 4 levels of security to authenticate Stored
Value Wickets and their data. First, Wickets utilize special
security tags having an invisible encrypted 32-bit password
protection, unique to each Wicket, required for data access.
Second, data stored in each block is authenticated by a
proprietary cipher algorithm. Third, each Wicket holds a property
specific Site-ID which must match that configured in the WR99 to
be accepted. Fourth, the host controller must first be validated
by a challenge/response sequence before the WR99 will write
anything to a Wicket.
has a polling based protocol wherein the WR99 status is always
returned. If a Wicket has just been freshly read then its UserID,
and balance information are also appended to the poll response.
The protocol supports commands for debiting and crediting the
various balances, for controlling the LED color and blink
properties, and determining the version of the reader firmware.
Status flags are used to indicate success or failure of write
operations. Management of the account and bonus balances (real
money versus non-refundable free play credits) is handled
automatically by the WR99 such that a debit command will first
debit what it can from the account balance, and then debit the
bonus balance. For security reasons more detailed information
regarding the WR99 protocol will only be shared with OEMs
executing a suitable NDA.
