How it's made

Challenges we ran into During development, we encountered several challenges that required creative problem-solving. One major issue was unstable Wi-Fi connectivity, which our NFC reader depends on; this became problematic in certain venues, prompting us to explore alternatives like LoRaWAN for more reliable communication. We also faced a technical hurdle when two NFTs were minted simultaneously on Base, causing errors due to how our smart contracts were constructed—this was promptly resolved by adjusting the contract logic. Additionally, prototyping the second generation of our Panatak NFC reader was limited by budget constraints, so we improvised by salvaging spare parts to minimize costs and continue development.
