Stop Checkout Chaos: Why I Built SnartCard

by

Love them or hate them, loyalty programs and store memberships are everywhere. While privacy debates often steal the spotlight, there’s a practical problem that drives me crazy every time I shop:

The scene you know all too well:
You’re at the checkout. “Are you a member?” asks the cashier. You rattle off your phone number… they type it wrong… you repeat… it fails… you find your phone to lookup your wifes number… it fails too…  Time wasted. The line behind you grows. Everyone gets annoyed.

The problem? Almost every store uses your phone number as ID. The technology to make this simple exists—barcodes!—but the solution was missing.

So I built SnartCard: An app that does one thing, and does it perfectly.

What SnartCard Does

  • Stores your membership numbers: Save your phone numbers (yours, your partner’s, your kids’) once.
  • Shows them as a crisp barcode: Instantly, with one tap.
  • Switch numbers with a swipe: Your wife’s a member here? Swipe. You’re a member there? Swipe.
  • Instant access: Add a direct home-screen shortcut. No menus. Open the app → barcode appears immediately.

Yes, other barcode apps exist. But none are built specifically for this:
Showing exactly the number you need as fast as possible—no delays, no extra steps. That’s SnartCard’s entire purpose.

The Result? Pure Magic (and Smiles!)

  • For you: “My number? Just scan this!” Beep. Done. Payment starts instantly. No typing, no mistakes.
  • For cashiers: “Oh, so smart! This saves us so much time!” They love it. Less stress, faster customers.
  • For the queue behind you: They’ll never know why it was so quick—but they’ll be grateful.

Simplicity, Privacy & Two Versions

  • Privacy focused: The app collects zero personal data (beyond standard Google data in the free ad-supported version).
  • SnartCard Free:
    Stores one number. Shows ads. Perfect for testing or single-store users.
  • SnartCard Full (Paid):
    Stores unlimited numbers. No ads. Swipe to switch. For frequent shoppers.

Try It Yourself! (Android Only)

Tired of spelling out your number at every register? Give SnartCard a shot!

In short: SnartCard is the answer to an everyday frustration. It does one thing: Gets you through checkout fast—with a smile. It doesn’t need to be complicated. ✨
