Verifone P400 Setup

Now that you’ve purchased your Verifone P400 reader from, it’s time to setup and start using your device with WooCommerce. In this guide, we’ll walk you through connecting your reader to Wi-Fi, registering your reader, and completing a transaction.

You should have already installed the WooCommerce and WooCommerce Stripe Gateway plugins on your WordPress site, as well as the Terminal for Stripe and WooCommerce plugin. If you haven’t installed and activated the Terminal plugin, please select the appropriate button below to see the installation and configuration guide for the applicable version. Our free article explains how to install and setup the FREE Terminal for Stripe and WooCommerce, while our pro article covers how to install and setup the PRO Terminal for Stripe and WooCommerce. You won’t be able to setup or operate your reader until you have completed all necessary steps from the plugin setup guide.


Setting up your Verifone P400 reader

Connecting to Wi-Fi

  1. Once out of the box, remove the plastic cover from the back of your reader.
  2. Connect the included patch cable to the back of the device, and then replace cover.
  3. Connect the AC adapter to dongle (i.e., the female end of the patch cable), connecting the other end to a power source.
  4. Type the code “09434” (0wifi) into the reader to view network settings.
  5. Select desired network and connect.

*Note: Your reader may not support Wi-Fi right out of the box. If this is the case, connect an ethernet cable from the dongle to your router, and then power up your device. This will automatically install the necessary firmware.

  1. Enter the code “07139” into the reader.
  2. The stripe background should now appear on your reader’s display, along with a three word, hyphenated sentence. This is your registration code. You will need this code to register your device with WooCommerce.

Registering your device

  1. On the plugins section of your WordPress site, find the ‘Terminal for Stripe and WooCommerce’ plugin, and click the ‘Settings’ button. This will take you to the ‘Payments’ tab of the WooCommerce ‘Settings’ section. On this menu, you’ll be able to enable, rename, and manage your readers.
  2. Under ‘Readers,’ click the ‘Add Reader’ button.
  3. Enter the three word, hyphenated registration code exactly as it appears on your reader.
  4. Now, you’ll be prompted to give your reader a name. If you plan to operate more than one reader at once, you should make this name recognizable to avoid confusing the readers while checking out multiple customers.

Now that your device is registered, you are ready to start performing credit card transactions using the Verifone P400 reader.

Operating your Verifone P400 reader

Completing a transaction

  1. First, click ‘add to cart’ on the selected item.
  2. Once all items have been added, click ‘View Cart,’ and then ‘Proceed to Checkout.’
  3. If you are using the Free version of the Terminal plugin, the information now visible under ‘Billing Details’ will describe the cashier. WooCommerce will use this data to note which user performed the transaction. In the Pro version, you can choose to associate the purchase with a customer account, instead storing cashier info as metadata.
  4. Next, scroll down and select ‘Stripe Terminal’ as the payment method.
  5. Select the name of the reader you are using for this transaction. This will put the terminal in waiting mode, as the reader activates and prompts the customer to initiate payment. The Verifone P400 accepts payment in the form of dipping, swiping, contactless RFID, samsung pay, google pay, and apple pay.

If the card is declined, the transaction is cancelled by the cashier by pressing ‘esc’, or there is no activity for 30 seconds, the reader will deactivate, the order will cancel, and the terminal will exit waiting mode. Once the payment has gone through, the transaction will be complete.

The Verifone P400 setup procedure is now complete. You are now ready to start using your reader to perform in-person credit card transactions for your business, directly from your WordPress site.
