Franchise car wash: the membership token is the balance sheet.

Tunnel car wash operators grew by turning single-purchase customers into monthly members, and the member — not the tunnel — is now the asset. That makes the membership tokenization system (license-plate recognition + stored card + tier) the balance sheet, and the vendor decision behind it a lock-in that survives a change of ownership better than any physical piece of the wash.

Five vendor camps, and each treats the membership token differently

The map is smaller than the trade-show floor suggests. DRB ships two POS/membership platforms — SiteWatch and the newer Patheon — with LPR and RFID member recognition integrated with the Beacon mobile app. Sonny's Enterprises launched Quivio on November 3, 2025 per its own BusinessWire release — an integrated software-plus-hardware suite with a 2026 roadmap that adds an AI sales-coach module and a maintenance module. Innovative Control Systems (ICS) launched its own AI-LPR in March 2025 and supplies unattended payment kiosks. Tommy's Express runs a proprietary in-house stack across its franchise network. And WashCard (owned by D&S Car Wash Equipment) covers cashless in-bay automatic entry. The camps overlap on capability; they diverge sharply on whether your membership token is portable when you switch platforms.

Sonny's Quivio and WashMetrix reset the incumbent conversation

Sonny's acquired WashMetrix on August 20, 2025 to accelerate its business-insights layer, then launched Quivio ten weeks later as the umbrella integrated suite. That's a meaningful signal for any operator whose next contract cycle sits with a competing vendor: the fully integrated software-plus-hardware pitch is now a two-horse conversation (Sonny's and DRB) with Tommy's operating its own path outside the vendor market and ICS holding a strong POS-plus-kiosk position. It doesn't mean an operator on ICS or DRB should switch — it does mean the vendor's product roadmap and integration priorities are being defined against a live competitor for the first time in a while. Read the roadmap, not the marketing.

Buyer-side. Supplier-paid. Buyers pay zero. Compensation has zero weight in the Cardinal Index scoring inside the Cardinal Method. Specific commercial terms live only in the private Decision Memo a buyer signs, never on this page.

AI-LPR is table stakes; the edge cases decide member experience

DRB shipped AI-LPR across both SiteWatch and Patheon with a claimed 99.9% accuracy on its vehicle identification page. ICS shipped its AI-LPR in March 2025. Tommy's ships it as part of the proprietary stack. The headline accuracy number is not the operating number. Every edge case — dirty plates, snow-state buildup, temporary paper tags, out-of-state formats, motorcycles — pushes the miss rate higher, and every miss at the entry arch is a friction event for a paying member. At three sites, edge cases are handled by the tech waving the car through. At 40 sites, edge cases are handled by whatever the software escalates to a manager dashboard, and if the escalation flow is thin, a small percentage failure becomes a measurable retention problem. The buyer screen isn't “what's your LPR accuracy.” It's “show me the reconciliation between what the LPR read, what the mobile app account said, and the car that actually entered the tunnel — and how often those three disagree.”

At 40 sites, the network segmentation question stops being IT

A multi-site tunnel operator runs POS terminals, membership APIs, mobile-app backends, tunnel PLC controls, chemical-usage sensors, and reclaim-monitoring sensors — and many run all of those on one flat property LAN. That was survivable at three sites. It's not survivable at 40. A flat network means one compromised endpoint — a compromised POS terminal, a phished manager workstation, a vulnerable IoT sensor — touches everything from card data to the chemical dosing on the tunnel arch. Segmenting properly (VLANs at minimum, physically separate circuits at higher-traffic sites) is an architectural project, and the vendor's answer to “how is our network segmented” often reveals whether the operator was ever asked. Meanwhile the membership-token side has its own migration trap: stored payment tokens are held by the processor embedded in the current POS. Switching platforms typically means re-authorizing every recurring member, which — at 40 sites and tens of thousands of members — is a multi-month revenue leak that shows up nowhere in the vendor demo. Treat the LPR + POS + processor triad as the migration-blocking asset it is.

The 5-item vendor screen

1. If we swap our POS/membership platform, do we lose the LPR-linked membership tokens — or does the new vendor import them via a documented migration path?
2. Show us the last 30 days of membership churn by cancellation reason across all sites, with card-decline recoveries broken out.
3. What's the chemical-usage-per-car curve for the past 12 months at each site — and where is a sensor drifting?
4. How segmented is our PLC network from our POS network — one flat LAN, or actually isolated?
5. Show us the reconciliation between the mobile app account, the LPR match, and the car that entered the tunnel — how often they mismatch and how it surfaces to a manager.
