In a typical retail business, when processing a sales transaction and a customer pays in cash, the cashier usually receives the money and places it in the cash drawer. This process can lead to cashier errors, as the amount of cash received may not match the amount that should be paid by the customer.
To address this issue, Innovative Technology provides self-checkout cash machine hardware that can help streamline the sales transaction process. With a cash machine, the system can automatically determine the amount the customer needs to pay and accurately calculate the total amount of cash received.
DealPOS can be connected with Innovative Technology Cash machine, allowing your sales transactions to be processed faster and more accurately. To connect DealPOS with a Glory cash machine, follow the guide below.
I. Installing the ASP.NET Core
Step 1. Install the ASP.Net Core in Your computer device
Install the ASP.NET core based on Your Windows version.
For Windows x64:
Download ASP.NET Core 10.0 Runtime (v10.0.11) - Windows x64 Installer
For Windows Arm64:
Download ASP.NET Core 10.0 Runtime (v10.0.11) - Windows Arm64 Installer
Step 2. Open CMD (Command Prompt) and Execute Command
After you've done installing the ASP.NET Core, you must execute this command in the CMD:
dotnet dev-certs https --trust
II. Preparing Machine & Running the Middleware
Step 1. Cash Machine Requirements
Before launching the middleware:
Ensure the cash machine is powered on.
Ensure the machine is connected to the computer via USB or other supported interface.
Confirm there are no hardware errors on the machine.
Step 2. Launch Middleware Application
Run the BAT file from the extracted folder.
Middleware opened.
Do not close these windows while the system is operational.
Step 3. Validate Runtime Status
Check the CMD windows and ensure:
No errors are displayed
No missing file warnings
No initialization failures
Step 4. POS Account Requirement
Ensure you have an active DealPOS account and subscription before continuing.
III. Middleware Dashboard Overview
Step 1. Accessing the Dashboard
Open a browser and access the URL:
Upon loading, the application automatically redirects to the Home page.
Step 2. Dashboard Structure
The dashboard contains two main menus:
Home
All Money in Machine
Withdraw Money
Setup
Communication & machine configuration settings
IV. Middleware Configuration
Step 1. COM Port Configuration
Navigate to the Setup tab.
Check the field “ComPORT” (default: COM3).
Validate this against your system:
Open Device Manager
Expand Ports (COM & LPT)
Identify the COM port assigned to the cash machine
If the machine uses another port (e.g., COM4), update the value on the dashboard accordingly.
Step 2. Editing appsettings.json (CORS Configuration)
Open from middleware folder:
appsettings.json
Locate the allowCORS array and add your DealPOS domain, e.g.:
Insert this entry as the last item in the list, separated by a comma.
Save the file.
Step 3. Routes & Inhibits Configuration
Within the Setup tab, two tables are available:
Routes
Defines currency denominations accepted by the machine.
Inhibits
Defines denominations that the machine can dispense.
The system provides default IDR denominations.
If you require custom currencies, you may edit these tables by edit each row or clicking "Tambah Nominal" button to create a new one or use bulk configuration through:
/middleware/json/banknotes.json
V. Customizing banknotes.json
Open file:
banknotes.json
This file contains two configuration arrays and currency metadata.
Step 1. InhibitsConfig
Used for withdrawal denominations.
Editable properties:
Nominal
Currency
Important:
Nominal values must include two extra zeros at the end.
Example:
1,000 IDR → input as 100000
Set:
"Inhibit": false
Step 2. RouteConfig
Used for accepted denominations.
Properties:
Nominal
Currency
Route → must always be
"1"
Step 3. Primary & Secondary Currency
Below the arrays:
PrimaryCurrency: Main POS operating currency
SecondaryCurrency: Secondary machine-supported currency
ExchangeRate: Conversion rate from primary → secondary
Calculate:
falseif primary currency value > secondary currency valueControls exchange calculation logic
Example:
1 USD = 10,000 IDR
Thus:
"ExchangeRate": 10000"PrimaryCurrency": "USD""SecondaryCurrency": "IDR"
Step 4. Apply Configuration
After editing, save the file.
Restart Required:
Any configuration changes require:
Closing all 3 CMD runtime windows
Re-running the BAT file
Reloading the dashboard
VI. Turn On Middleware App
Step 1. Establish Connection
Go to Setup → click Open Connection.
A green success notification will confirm the connection.
Step 2. Start Devices
Click Start Devices (green button).
Wait until a green success message appears.
Middleware configuration is now complete.
VII. POS Setup — Payment Method
Step 1. Open Setup Menu
Navigate to Setup → Payment tab.
Step 2. Add New Payment Method
Click Add.
Fill in:
Payment Method Name
Type: Cash
Subtype: Machine
Note:
A second payment method with the same type and subtype is not allowed.
Click Save.
VIII. POS Setup — Currency
Step 1. Open Currency Menu
Go to Setup → Currency.
Step 2. Create or Set USD as Primary Currency
If USD is not listed:
Click Add
Enter:
Currency Name: USD
Symbol: $
Exchange Rate: 1
Check Primary Currency
Click Save.
IX. POS Setup — Connecting POS with Middleware
Step 1. Establish Connection
Navigate to Sell → More Action → Cash Machine.
Click Connect.
A green toaster confirms success.
If an error appears, review previous configuration steps or contact customer support.
X. Simulation Procedures
Step 1. Machine Simulation via Middleware
All Money in Machine
Displays:
Country Code (Currency type)
Value (Denominations in syste )
Stored (Quantity per denomination)
Withdraw Money
Allows withdrawal simulation by entering:
Amount (Amount to withdraw)
CountryCode (Currency type)
Example:
IDR 50,000 × 2 + IDR 20,000 × 1 = 120,000 IDR
To withdraw:
Currency: IDR
Amount: 120000
Click Get Money
XI. POS Transaction Simulation (Primary Currency - IDR)
Step 1. Create Sell transaction
Step 2. Choose cash machine payment method
Step 3. Input cash/money into the Cash Machine
Step 4. Payment Accepted and Completed
Important note: If the required change denominations are available in the Cash Machine, the change will be dispensed automatically. However, if the denominations are not available, a notification will appear as shown in the screenshot above.
XII. POS Transaction Simulation (Secondary Currency - USD)
Step 1. Create Sample Transaction
Create a transaction worth USD 20
(≈ IDR 200,000 at 1 USD = 10,000 IDR).
Step 2. Process Payment
Click Pay → Choose Cash Machine.
Step 3. Insert Cash
Insert IDR 100,000.
The system registers 10 USD received.
Insert another IDR 100,000 to complete payment.
Step 4. Automatic Change Handling
If change denominations are available → machine auto-dispenses change.
If not available → POS displays a warning to give manual change.
Note:
Automatic change is fully supported only when using one unified currency.
XIII. Completion
Your Cash Machine Middleware and POS integration is now fully installed, configured, and ready for production use. All simulations confirm that currency conversion, denomination routing, and machine behaviors are functioning as designed.
