Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getTransactionNumber([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setTransactionNumber([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:

Remarks
This field contains a terminal-generated transaction sequence number to be submitted in all authorization request messages. This number is echoed back to the terminal in the ResponseTransactionNumber for the purpose of assisting in the matching of authorization request and response messages. This value must be in the range 0001 to 9999 and should be incremented on each authorization request message. This number should automatically increment from 9999 to 1. 0 is an invalid transaction number.
