PopKnock is a newly launched mobile app designed to provide a convenient and efficient platform for various types of businesses, while helping users access a wide range of services all in one place.
Currently, the platform covers a variety of sectors, including restaurants, home renovation, insurance brokerage, health and beauty, education, and more. Through PopKnock, users can shop online, book services, contact businesses, purchase event tickets, and use digital membership cards.
PopKnock offers three easy ways to adding digital membership cards:
- Automatically generate a digital membership card using your membership ID and email.
- Select a business from the platform's merchant list, then enter your membership ID to generate the card.
- Upload a photo of your physical membership card.
- Avoid issues with lost or forgotten physical cards.
- Instantly generate a digital card upon registration—no waiting required.
- Some merchants show card expiration, renewal, and member benefits—PopKnock keeps track of them all and reminds you when it's time to take action.
- Built-in Geo-Card feature shows available cards based on your current location for efficient use.

When prompted, choose your preferred location setting. We recommend selecting "Allow only while using the app.

In practice, clicking on "Geo-Card" may lead to one of the following screens:
- No Linked Membership Cards: If no cards are linked to your current location, you'll see a message saying "No associated membership cards." Here, you can also tap to add a card.
- Linked Membership Cards Found: If you're near a location where you've already added a membership card (e.g., Orential Supermarket), the card will automatically appear when you tap Geo-Card for quick access.
PopKnock supports adding the Geo-Card feature as a widget on your phone's home screen for faster access.
- Long press the PopKnock app icon and select "Widget" from the shortcut menu.
- Once enabled, the widget will appear on your home screen. Tapping it will directly open the relevant digital membership card without needing to open the app

- Card Verification: Some cards (e.g., CASTP) support QR code scanning for verification.
- QR Code Validity: Codes auto-refresh every few minutes, so screenshots may expire—use them promptly.
- Security Reminder: Some merchants may not accept screenshots; verification must be done via the app with the original digital card.
