This is the default screen the terminal rests on, so customers can get started right away. They can reload a card, sign up for a digital card, use a scanned card or pay with money. Once they enter a payment method, they go straight into the wash screen.
You could have a similar navigation screen with your own branding and styling. The options could be subscription signup, payment with debit or credit, or payment with a subscription.
A customer chooses an amount for the wash and proceeds to the payment terminal. The payment flow leads into the wash session.
Single-wash payment could sit alongside subscriptions. It would also provide a route for a member buying something their plan does not include.
The screen guides the customer while the payment is processed. Once payment succeeds, they can continue.
For membership signup, Stripe would be the proposed subscription billing service. Membership access would be connected to the subscription status. This wash-payment screen illustrates the guided experience; the subscription checkout would be designed for your system.
Customers enter their name, email and phone number on the touchscreen to create a digital account. Their phone number identifies the account, so they can sign up without a physical card or help from an employee.
The same account signup system could easily be used with subscriptions as well. Customers could create their account, then link it to a subscription and use their phone number to identify themselves when they visit.
For customers joining at the counter, the employee scans the RFID card on the Start Scan screen. The reader enters the card number just like a keyboard; staff then confirm it to look up the card.
This could be the start of staff-assisted subscription signup, using a physical card to identify the customer’s account.
If the new card is not found, it takes the employee to register the card. The customer-details screen lets staff enter the customer’s name, phone number and email. This completes the assisted signup story: scan the card, create the account and add the customer’s details.
Staff could use this same account signup system to help customers join a subscription. Both self-signup and signup at the counter would give customers an account to use when they visit.
The touchscreen gives customers a way to enter their number or scan a card. They can identify themselves without asking an employee for help.
Proposed member journey: enter your phone number, then enter your PIN. The system would find the membership linked to that number.
A simple keypad lets the customer enter a private PIN before continuing.
For your subscription flow, the PIN would help confirm that the person using the phone number is the account holder. After verification, the system would check their membership.
This is the unattended manual wash screen. The customer chooses a wash function on the touchscreen. The session shows the available funds, cost and elapsed time, with a stop control to finish.
For members, this screen could show what their plan includes and which extras cost more. Your rules would determine which services they can start.
When the available funds run out, the customer can top up to keep washing or choose to finish. Whether they started with a bank-card payment or a wash card, the screen guides them through adding funds and continuing their wash.
For subscriptions, a similar process could let members buy extra usage when they reach a plan limit. You could also offer a stored balance for extras alongside the subscription.
This is the receipt screen. For an unattended manual wash, it appears after the customer completes the wash. It shows the wash charges and payment information, any remaining card balance where applicable, and the option to request an emailed receipt. For an automatic wash, this screen appears after payment; pressing OK raises the lift arm so the customer can enter.
A member’s summary could distinguish usage included in their plan from extra charges. Subscription billing receipts and wash-visit summaries would serve different purposes.
The customer selects an automatic-wash package and enters payment. The selected wash function is then sent to the controller queue, and the lift arm is raised so the customer can enter.
A subscription could include a particular package. You could also offer an upgrade to a higher package for an additional payment.
An online administrator can see the terminals and open the one they need to configure. Each terminal belongs to a location and has its own settings.
Your membership system could use the same central approach for all your sites. You would choose whether a subscription works everywhere or only at selected locations.
A terminal has its own services and settings. The operator can configure the equipment and services for that terminal through the online portal.
Different locations could offer different equipment while recognising the same member account. Membership rules would decide which available services are included and how often they can be used.
The network/IP address identifies the controller to contact. The slave ID identifies the device on that connection. The coil number identifies the output to switch—for example, the output that starts a wash function. These values can be configured online.
The proposed sequence is: recognise the member, check what their plan allows, then activate the equipment configured for that terminal. Each site and bay keeps its own equipment settings.

The Verifone UX700 is my recommended Stripe terminal for this system. It is designed for unattended use and is flexible in how it can be used: as the customer-facing POS on its own touchscreen, or as the payment terminal alongside a separate touchscreen computer. It accepts card payments and can work with a separate touchscreen computer. Its Android platform also supports developing a POS application for the terminal screen.
You could choose either layout, develop both together, or introduce them in stages across your sites.
On-terminal app deployment is subject to confirming Stripe support, enablement and app review for the chosen UX700 configuration.
