First, you will need to make sure any transactions belonging to the iButton’s previous user are removed from your “Current Transactions.” This can be done by extracting your pay periods until all of those transactions are gone from Current Transactions. (Otherwise, TimePilot won’t know whether a transaction belonged to the old user or the new user.)
When all of the former employee’s transactions are out of Current Transactions, you can delete the iButton number from that employee’s profile (or delete his or her profile altogether), freeing up the iButton. Then you can assign the iButton to another employee, just as if it’s a new one.
The procedure for adding employees varies by TimePilot system; for instructions for your product, please visit the software’s help files, which are available under the “Help” menu in TimePilot Central or under your product’s listing in our web site’s Support Center.
