When the end of the long screw comes out of the bottom of the T bracket, place the metal washer over the screw and then thread the thumb nut onto the end of the screw.
Using a Phillips head screwdriver, tighten the screw securely (but not excessively) into the thumb nut.
Installation Process Overview
Install Microsoft .NET Framework 3.5 SP1
Install Java for Windows
Install the STPI Secure Client software
Activate the STPI Secure License
Start the STPI Client for the first time
Configure the STPI Client as a Service
This document will cover the configuration required to operate SecureTable using the Maitre’D direct integration to the STPI client.
SecureTable is a universal middleware platform that provides an EMV-Compliant, Pay at the Table (PATT) processing solution that can be connected to a POS (Point of Sale) system. The solution can work in standalone mode as well as integrated to a Point of Sale (POS) system such as Maitre’D, Veloce, Squirrel, Aloha and Micros among other.
SecureTable uses a “Pull” architecture. This means that a payment terminal using SecureTable can initiate the transaction process by Pulling check data from the POS system. In other words, after the guest checks are printed and handed to customers, there is no need for the server to walk back to the POS workstation to apply payments and close guest checks. All payments, including credit, debit and cash, can be applied at the table side, and checks are closed automatically.
By comparison, a traditional "Push" architecture is a system where the transaction would be initiated from the POS system, and check data pushed to the payment terminal. In a table-service restaurant, this process often required the customers to get up and walk to the POS workstation to insert their payment card and enter their PIN using a tethered payment terminal.
The integration of SecureTable with various POS systems allows the payment terminal to retrieve guest check data from the POS System. Once a payment has been processed by the payment terminal, SecureTable sends the payment data back to the POS System for reporting purposes. Payment amounts, tip amounts and card brand used are all automatically transmitted to the POS system to allow for accurate reporting.
SecureTable and SecurePay can both be used on the same POS system. This allows merchants to use any combination of stationary Pay-at-the-Counter terminals and wireless Pay-at-the-Table terminals. SecureTable and SecurePay share a similar user interface which provides a consistent user experience for customers and employees.
If a third-party solution with tethered (wired) payment terminals is already in place and integrated to the POS system, SecureTable can still be used without worry. A configurable table-locking or invoice-locking mechanism prevents accidentally accessing guest checks that are being processed by a payment terminal through SecureTable. This means that establishments can, for example, use wireless payment terminals with SecureTable in the dining room while using tethered payment terminals for the cashier station, bar, pickup counter and drive-through windows.
With a direct integration, Maitre’D communicates directly with SecureTable’s STPI client through a secure socket connection without using drop-files. This allows Maitre’D to take advantage of all the features offered by SecureTable, without the limitations imposed by using the former TPI client middleware.
After you secure the T bracket to the terminal, you must insert the cables. This procedure explains how to install and secure the AC adapter and Ethernet cables; if you have additional cables, connect them to the appropriate port and use the same method to secure them in place.
Beginning with the AC adapter, inserting it in the terminal's cable guide on the left and connect the adapter to the Power port.
Insert the Ethernet cable in the terminal's cable guide on the right and connect it to the LAN port.
When the cables are properly seated in their ports, gently pull on the cables to remove any excess cable that is higher than the plane of the T bracket.
Place the 3-hole metal bracket over the cables, aligned with the screw holes in the T bracket and secure it in place using a Phillips head screwdriver to insert the two short screws.
Turn the terminal over and power on the terminal. The completed assembly should resemble the following:
Here is a quick overview of the entire installation and setup process:
Install/enable Microsoft .NET Framework 3.5 SP1.
Install the latest version of Oracle’s Java for Windows.
Use the STPISecure to installer to install the STPIClient software.
Install the STPIClient license.
Start the STPIClient application for the first time.
Configure the STPIClient to start as a service (Optional).
Configure your POS System.
Connect, power up and configure payment terminals.
By default, the payment terminals using SecureTable will communicate with the POS system over TCP port 9999.
Open TCP port 9999 on the corporate firewall.
Open TCP port 9999 on the Windows Defender Firewall on the POS system's Back-Office as well as on all POS workstations.
The wireless network (for wireless payment terminals) needs to be able to communicate with the POS System.
Each payment terminal needs access to the Internet.
The .NET Framework (pronounced as "dot net") is a software framework developed by Microsoft that runs primarily on Microsoft Windows. Microsoft .NET Framework version 3.5 Service Pack 1 is required before the STPISecure installer can be used to install the STPISecure client or other components, such as the RTI-SIPA plugin.
On Windows 10, starting with version 1809, Microsoft .NET Framework 3.5 SP1 is included as a standard Windows feature and enabled by default. However, older versions of Windows 10, Enterprise or IoT editions, could be missing this essential component. Here is the procedure to check whether .NET Framework 3.5 SP1 is installed and how to enable it on Windows 10:
Click on the Windows 10 Start button and type Control Panel.
The Control Panel app should appear as a search result. Click on Open.
Within the Control Panel app, click on Programs.
Under Programs and Features, select Turn Windows features on or off.
The Windows Features list will appear.
Look for the feature called .NET Framework 3.5 (includes .NET 2.0 and 3.0).
a. If this feature is not listed, install .NET Framework manually. (See below)
b. If you see a black square in this checkbox, .NET Framework 3.5 is already enabled and no further action is required.
c. If the checkbox is blank, enable it.
NOTE: The black square in the check box means that the feature itself is enabled, but that some optional components are disabled. The optional components are not required for STPISecure or RTI-SIPA, so leave them disabled.
Click OK on the Windows Features list. This will close the list and apply any changes.
Files may be copied and you may be required to restart the PC.
For versions of Windows prior to Windows 10 1809, or for some older Enterprise or IoT editions, Microsoft .NET Framework 3.5 SP1 may need to be downloaded and installed manually.
The full installer can be obtained from the official Microsoft download site here:
Microsoft .NET Framework 3.5 SP1
Download the file and double-click it to start the installation process. Follow the on-screen instructions and restart your PC as required.
IMPORTANT! If the link provided here does not work, please use your preferred search engine and look for "Microsoft .NET Framework 3.5". Be sure to download the files from the official Microsoft download site. For security reasons, please avoid non-Microsoft sources.
Before a license can be activated, it needs to be purchased and created for you. Please contact the PayFacto Boarding team or your local Sales Representative to purchase a STPISecure license.
After you have purchased a STPISecure license, the license file will be sent to you as a text file attachment via e-mail. The e-mail will come from the PayFacto Boarding Team or your local Sales Representative.
Save the file from the e-mail to your Windows Desktop. Typically, the file is named something like "Licdefault_12345.txt".
Rename the file to "Lic.txt". To achieve this, you can right-click the file and select the Rename option, or select the file and press the F2 key on your keyboard.
Move the file to the following folder:
C:\Program Files (x86)\PayFacto\STPISecure\STPIClient\
The license activation process is now complete.
This step is required to have the STPISecure client start automatically when Windows starts, and have it run silently in the background.
IMPORTANT! If you have already configured the STPIClient application shortcut to start automatically with Windows by copying its shortcut to the Windows StartUp folder, be sure to un-do this configuration before proceeding further
