I Made a PCB Business Card with NFC. Go Ahead, Reuse My Files!

Hey guys,
I think this is something eevblog folks would appreciate. Check out my latest PCB business card! It's made out of 2 layer 0.8mm FR4.

This business card has NFC capabilities and features the most common integrated circuit footprints found on circuit boards today. Three rulers of different measure are also included: 1/32in ruler, 1/5mm ruler, 1/10th ruler. A trace width and pin patch gauge are also included, along with the different resistor and diode package sizes. The good news, is it only cost me $0.66 each for 150 of em. That's not terrible considering paper business cards are $0.04-0.06 in quantities of 500. These are Electroless Nickel-Gold plated though. Can't beat that!

Here's a few shots:

This card was designed in Kicad 5.0. Kicad is free pcb design software that is quite good. I used to use eagle cad to design small pcbs but Kicad now fills that need.
The PCB design files are free to modify for personal use and fall under a creative commons license.

I'd love feedback from you guys. Let me know what you think!

lordium:
I like the idea! Wouldn't mind it if someone gave me one instead of the old boring paper one. But I would never carry these around though, seems too bulky for my wimpy arms.

SerieZ:
Your design looks very slick and I like the usability of it. Good Job!

I have been thinking about Designing something like that on my own for some time now, maybe not to give them away but to have one on my Desk for vanity purposes.  :-*
Have not gotten around doing it yet tho.

thinkfat:
Suggestion, make it double as a soldering exercise. Instead of just footprints, make it do something and put a link in the QR somewhere that leads to assembly instructions.

Where is the chip? I don't see it anywhere.
