This inexpensive NFC-Tag equipped keychain might be the solution!
It is meant to be attached to your luggage or anything else that would fit a keychain (on a zipper, key, bag, etc.). You can include the data you want (please check the capacity of your Tag), as it is stored on a NFC Tag.
The tags used are sized 20 by 10 mm. Please insert it, when the print pauses. This is already included in the G-Code.
It takes place at a height of 1.20 mm / Layer 12 (for the default profiles / 0.2mm nozzle/0.10 mm layer height)
After you have inserted the NFC Tag, please hit continue, either on the printer itself or Bambu application. This might also apply for other printers.
The NFC Tags are not available in the Bambu store, yet - still they need to be bought in advance.
You need NFC Tags that are rectangular, for instance one of those.:

Size is: 20 * 10 mm (Thickness is not worth mentioning)
I found a table which explains the differences between the different NTAG-Versions, storage is the main difference.
Ntag213 | Ntag215 | Ntag216 | |
Total storage (bytes) | 180 | 540 | 924 |
User storage (bytes) | 144 | 504 | 888 |
Maximum URL (Zeichen) | 136 | 488 | 872 |
There are different apps available, but i do recommend "NFC Tools":
After the app was installed its crucial to get an idea what you want to include in the NFC Tag data.
I recommend to add a V-Card to the tag or an URL/Mail address etc. Furthermore i would not store an adress, as it might be pose a security threat.
