How to try this card.
Three things to do with one sample card. It is a design study: the card and its stamps are valid nowhere.
Tilt the card
Move a pointer over the card, or slide a finger sideways on it: it leans up to 8° and the foil’s stripes catch the light. Scrolling up and down still scrolls the page. From a keyboard, Shine once sweeps it one way and back.
Flip it
Front and Back · stamps turn the card. The side you are not looking at is set aside for keyboards and screen readers; the panel repeats what both sides say.
Add sample stamps
Add a sample stamp turns the card to its back and presses one in. At 10 the card is full and the button says so instead of stamping.
What a sample stamp means
Nothing outside this page. You add the stamps yourself, so they prove no visit; the 10 rings and the free 11th cut show how a barber’s card works, not an offer. There are no points, prices or rewards, and Pangkas Tiang Merah does not exist.
What is kept, and how to clear it
One number, the stamps from 0 to 10, in this browser’s storage under collection-kilau-member-v1 (at most 256 bytes). No date, history, name, phone number or account; nothing is sent. Which side is showing is not remembered.
Start the card over asks first, then sets it back to 0. Clearing this site’s data in the browser removes it too. If the browser blocks or fills its storage, the stamps still work on the page and the card says they will be lost when it closes; if what is stored cannot be read, the card starts at 0 and says so.
Where the sample stops
Kilau is connected to no shop, till or wallet app, and shares nothing between visitors or devices. It is deliberately not a bank card: no chip, long number, expiry date, network mark, contactless symbol or magnetic stripe. A real loyalty card would need stamps given at the counter, its own rules and agreed storage, built separately.
