Counter Property

The counter.

Syntax

 ocra.getCounter([callback])
 ocra.setCounter( counter, [callback])

Default Value

0

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 getCounter([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 setCounter([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:

err.code
err.message

Remarks

This property specifies the counter.

If a counter is required this must be set before calling CalculateResponse and VerifyResponse. To determine if a counter is required assign OCRASuite to the OCRA suite and check the value of RequireCounter.

The counter value should begin at 0 be incremented until the maximum value is reached. After the maximum is reached the counter value should start again at 0.
