# Duplicate Transaction Options

### Duplicate Transaction Options

When using the SecureTable 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 disable the duplicate transaction on the terminal.

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

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

   * **Repost**

   * **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.
