This app scans and verifies KONG via NFC. 

To use the app you must have KONG and an NFC enabled iPhone. Simply tap to scan, hold the device against your phone.

The app will validate the corresponding token stored on chain against the KONG.

What’s New

Version 1.2.0

The Kong printer's 1.2.0 release. This adds "Full verification" and "Quick verification" modes.

Full verification challenges the secure element on a Kong note to sign the current blockhash. This mode completely ascertains the authenticity of a Kong.

Quick verification checks the note to see that a recent blockhash was signed. A recent blockhash signature is a reasonable assurance that a given Kong is genuine. Quick Verification is less sensitive to things like alignment and battery level.

Looking forward to the future

Received my first bills today, the printers did a beautiful job with the PCBs, the colors, designs, and gold plating is really well done and looks like it belongs in the year 2022 :)

However, maybe I’m missing something, because scanning resulted in all verification failures. I preferred it failing fast compared to when the app would just “hang” causing me to grow impatient and quit and restart.

The bills are quickly recognized and identified as their face value, but I get the “verification failed” frowny face

Am I supposed to do something with the black chip card that came with the order?

Thanks for your work, looking forward to an update !

If it helps your debugging, my bills are Series 2019 0x00::47
