Parameters

• sequenceNumber
  Sequence number for approval.

• amount
  Purchase amount for approval.

• taxOthers
  Tax and other amounts for approval.

• timeout
  The maximum wait time (in milliseconds) until the response is received from the CAT device. WaitForever, 0, and positive values can be specified.

Remarks

Normal purchase approval for amount and taxOthers is intended as the approval specified by sequenceNumber.

When timeout is WaitForever, time-out never occurs and the device waits until it receives a response from the CAT.

AuthorizeSales may cause a PosControlException to be thrown with the following ErrorCodes.

Value	Meaning
Illegal	An invalid timeout parameter is specified.
Timeout	No response was received from CAT during the specified timeout time in milliseconds.
Extended	The detail code is stored in ErrorCodeExtended.
Busy	The CAT device cannot accept any commands now.
