CardFoursa
ABOUT

We didn't reinvent the tap. We just made it useful.

CardFoursa turns NFC into something a small business can actually run. The chip is cheap; the system behind it is the point.

THE STORY

It started in a café.

There was a QR code on the table. Nobody scanned it. Open the camera, focus, trust the link that appears — small but real friction. The waiter repeated the same sentence at every table.

NFC removed that friction entirely. But most cards on the market made the same mistake: the handle was written straight onto the chip. Change your Instagram account and two hundred cards became landfill.

That's why we started CardFoursa. What we sell isn't a card — it's a changeable link and a tap report, with a card as its physical face.

HOW WE WORK

Three rules.

01

No order without a sample

You can't judge read distance or print quality from a photo. Hold it first, decide after. It costs us something and insures you.

02

Nothing that fails on iPhone

Half your customers use one. We don't stock cheap chips like MIFARE Classic that simply don't work on iOS.

03

Tested before locking

Every card is read on both Android and iPhone after encoding, then the chip is closed to writing. Nobody can overwrite your card.

PRODUCTION

How a card is made.

  1. 01

    Chip sourcing and verification

    Random cards from each batch are read to confirm the chip really is an NTAG.

  2. 02

    Print file preparation

    Bleed, safe area and CMYK conversion are checked; text is converted to outlines.

  3. 03

    Print and finish

    UV print on PVC or a domed epoxy top. No metallic ink — it weakens the signal.

  4. 04

    Encode, test, lock

    The link is written, tested on both platforms, then closed with password protection.

  5. 05

    Packing and dashboard handover

    Cards are boxed, your dashboard access opens, and a QR guide ships with them.

The next step is simple.

Tell us about your business and we'll tell you which card fits. Not a sales call — a technical conversation.
