In order to know if a transaction was manually entered, changed, or deleted, we would need to generate a transactions report. This report is capable of showing us the user who has made the change, the time and date of the transaction being changed, the device that was in use for the punch and the actual type of change that had occured.
Each individual transaction on our timecard screen also has a Manual field that displays 'Yes' if the transaction was added or modified by a user or 'No' if it just came from the device and has been untouched.
The transactions tab found next to the timecard will show us the transaction in more detail as well as displays the user who had last made any edit to it.
