Such a creative product. ### 4/5 — Looking forward to the future *2019-12-21* 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 ### 5/5 — Works great!
