1. Buy required NFC Tag:

An ntag216 is used as the NFC tag.
This can later be easily programmed and read using your smartphone.
A total of 888Bytes of memory is available.

2. Customize your Card:

Open the "NFC Business Card.stl" File in any Slicer where you can add Text to your Modell (e.g. OrcaSlicer or BambuStudio) and customize your Card.
Otherwise, you can also open the “NFC Business Card.step” file in the 3D software of your choice and add text and icons there.

3. Slice your Card:

Important slicer setting:

Layer height: 0.12mm
First layer height: 0.2mm
Support: off

Add a pause at Layer 5 (or at height 0.68mm).

4. Print it!:

start printing and wait until the first four layers are printed successfully.
Now you have to place the NFC tag with the adhesive side in the hole in the middle and press it lightly.
Now you can resume your print.

5. Programm the Card:

To program the card you only need your smartphone and an NFC app (I recommend using NFC Tools https://play.google.com/store/apps/details?id=com.wakdev.wdnfc )

Go to the Write tab and then press Add a record.

Here you can, for example, select URL/URI to link to a website or Text to simply save text on the card (note, the memory is limited to 888 bytes, so keep it short).
Otherwise there are many other options open to you, get creative!

When you have added all the data, click on Write / XXX Bytes and then hold your card to your phone.

6. Enjoy using!:

You can also use your cards as a ToDo list, for example.
Put a card on your desk, one in the workshop, one in the kitchen, etc.
Then, for example, write on the card what you still want to buy or what you need to do in the garage.

Your family members can also easily read the notes and add their own.
