Receipts which have been fully paid off are automatically locked to prevent people from tampering with them. Receipts are generally only unlocked if there is a balance on them.

If this is a new transaction it is better to create a new receipt (See How To I Create A New Reciept?)

To Unlock an old receipt...

• Double Click the Padlock Icon on the Till Receipt.
• Enter Your Pin Number.
• The receipt is now unlocked.

To Re-lock the receipt, repeat the above three steps. The button is shown below, with the receipt in locked mode.
