Frequently asked questions

How does the tap-to-pay 500 bill work? +

Slide your NFC credit or debit card inside, snap the back plate closed, and tap to pay like normal. The NFC signal passes right through the 3D printed shell — no need to open it at checkout.

Will my card fit? +

The MoneyPoly™ 500 fits standard-size NFC credit and debit cards. Your card is not included — you bring the card, we bring the fun.

Is the AirTag included with the mounts? +

No — the Apple AirTag is sold separately (about $29 from Apple). Our mounts hold and conceal the AirTag you already own.

How durable is 3D-printed gear? +

We print in high-strength materials and test every design in real use. Minor layer lines are normal — they're the fingerprint of a made-to-order piece — and every unit is inspected before it ships.

How fast is shipping? +

Free U.S. shipping on every order. Orders ship within 1–3 business days with tracking included.

What if I don't love it? +

Return it within 30 days for a full refund — no questions asked. You also get email support directly from the designer.
