# Duplicate Transaction Options

### Duplicate Transaction Options

When using the SecurePay module, you can choose the terminal's behavior when a communication issue causes a transaction to appear a second time (a duplicate version). By default, the terminal reposts the transaction, but you can choose to automatically void or disable the duplicate transaction on the terminal.

#### **To set the terminal's duplicate transaction behavior:**

1. From the main screen, touch the **Menu** button.\

3. Scroll to the **Semi-integrated configuration** section and touch SecurePay options.\

5. Touch the option you wish to use for the terminal:

   * **Repost**
   * **Auto Void**
   * **Off**

6. If you have more than one terminal, repeat steps **1** to **5** for each additional terminal to configure the terminal's behavior for duplicate transactions.
