For car washes that run on regulars

The loyalty card
they can't lose.

Platecard turns a number plate into a punch card. Type the plate, tap the package, and the counter knows how close every regular is to a free wash. It runs in the browser on your counter device: no account, no sign-up, nothing to install.

AB12 CDE

Paper cards end up in the wash.

They go through the laundry, live in the other car, or never come back out of the glovebox.

Somebody forgets to punch one on a Saturday, and a regular is a wash short.

At closing, nobody can say how many Deluxe washes went out or how many free ones were given away.

Three taps at the counter.

  1. Type the plate.

    Spaces, hyphens and capitals don't matter: "ab12 cde" finds AB12CDE. Half a plate lists the likely matches, and an empty search shows the eight regulars you saw most recently. No card yet? The plate is already filled in on the new one.

  2. Tap the package.

    Pick Basic, Deluxe or Ultimate (or whatever your menu says) and press Record paid wash. One punch, saved on the spot. Tapped the wrong one? Undo takes back the last wash recorded today.

  3. See where they stand.

    The card shows every punch as a circle, says when a free wash is ready, and tells you how many visits until Silver or Gold. That's the thing worth mentioning while they pay.

Everything a punch card should have done.

Ten washes, one free. Or whatever you offer.

Set how many paid washes earn a free one, anywhere from 2 to 50. Free washes bank up and never expire. A free wash doesn't earn a punch, and it can go on any package.

Bronze, Silver, Gold.

Every visit counts toward a tier, paid or free. Silver starts at 10 visits and Gold at 25 until you change them. Tiers are a label, not a discount: a reason to say thanks by name.
