General
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.

Security
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.

Protocol
The WR99 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.
