BarcodeReadComplete trigger

Does anyone know of a BarcodeReadComplete trigger?  I have 2 fields.  After reading a barcode in the 1st text field, I want to automatically set focus to the 2nd text field.

I can't use ".on('change'" on the 1st field, because you would have to change focus to trigger it.

I can't use ".on('input'" because that changes after the 1st character is read

A lot of the barcode scanners can be configured to send an "Enter/Return" at the end of the barcode data.

Input fields don't know if it was a bar code reader that filled them. However, they often send keystrokes to fill input fields. So, you might be able to watch the keyup event and try to figure out when the bar code reader is done. You might be able to configure the reader to add an extra keystroke that you can watch for. You might even be able to get it to send a tab after the numbers have been entered. Or, you could have it send an invalid character that you could sniff for using keyup and then change focus yourself.
