INTRODUCTION

Overview 

In its latest commitment to improving the government’s financial management system, The Bureau of 

the Fiscal Service (Fiscal Service) Over-the-Counter Division now offers an Integrated Solution for 

Card Processing (Card Processing) within OTCnet to agencies who want to collect credit and debit 

card payments as part of their collections portfolios. The OTCnet Integrated Solution is a credit, debit, 

and Visa/Mastercard gift card payment method that incorporates the current Card Acquiring Service 

(CAS) process. With the addition of the Integrated Solution, OTCnet is the only one-stop-shop 

payment option for agencies over-the-counter collections needs, seamlessly offering Cash, Check, 

and Card processing without needing to access multiple applications.

To process in-person card payments, Fiscal Service will support the Verifone MX925 (MX925). The 

MX925 is on the forefront of card transaction technology, offering customers the ability to swipe, 

insert, or tap their card to make a payment. Bringing this technology to agencies will enable users to 

process a customer's payment securely and quickly, minimizing lines at the counter and wait time in 

agency locations.

About the Guide 

Fiscal Service has designed the following connection guide to help you and your agency complete 

equipment set-up of the MX925, enabling it to process debit and credit card transactions. Specifically, 

the connection guide provides step-by-step instruction on how to assemble, power up, and connect 

the MX925 to OTCnet, see Figure 1 below.

Connecting the Verifone MX925 Terminal to the Internet

The MX925 terminal requires an internet connection in order to process credit and debit card 

transactions1. The OTCnet Team recommends using a wired connection; the connection steps are 

outlined below:

1. Connect a category 5 (CAT5) or greater to the leftmost ethernet port on the backplate of the 

I/O (input/output) block within the MX925 terminal. See Figure 3 below:

Figure 3. Ethernet Port Connection

2. Plug the other end of the ethernet cord into an ethernet wall jack or internet router. 

NOTE: If connecting to an internet router, ensure the cable is connected into the WAN port.

3. If the I/O block is not already inserted, insert the I/O (input/output) block into the back of the 

Verifone MX925 terminal. See Figure 4.

Figure 4. Insert the I/O (input/output) Block into the Back of the Verifone MX925 Terminal

NOTE: Please allow for approximately five minutes for the Verifone MX925 terminal to boot up before 

proceeding to the next steps.

1 We recommend contacting your agency Network Administrator and/or IT Administration to ensure your network settings are enabled to allow 

network connection to the MX925 terminal.

After establishing an internet connection, it is time to configure the terminal.

Configuring the Verifone MX925 Terminal

Once your Verifone MX925 terminal is powered up and connected, you will be prompted to complete 

the following steps before you are able to process transactions.

1. Request Verifone push the SCA (Strong Customer Authentication) Configuration file to the 

Verifone MX925 terminal. Please allow a few moments for this to download and process.

NOTE: The Merchant Identification Number (MID) and Terminal Identification ID (TID) need to be 

setup in CAS/Worldpay prior to sending this request to Verifone.

2. Complete on-screen set-up steps of the Verifone MX925 terminal:

a. Enter your Merchant Identification Number (MID) provided by Verifone to your agency’s 

point of contact via email. When prompted, re-enter the MID.

b. Enter your Terminal Identification ID (TID) provided by Verifone to your agency’s point of 

contact via email.

c. Enter your LANEID (same code as the TID).

NOTE: If your agency already has the Verifone MX925 terminal, you will need to: 

1. Request a terminal reset from Verifone.

2. Submit a new CAS application by visiting the CAS webpage on the Fiscal Service website. 

Once your CAS application has been approved with a new Merchant Identification Number 

(MID), you may continue with the next steps.
