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
Cancellation 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 response from the CAT.
AuthorizeVoid may cause a PosControlException to be thrown with the following ErrorCodes.
