Coding Assignment Help Cards-Control.appCards-Control.app's answer:
Cards Control was born from a simple frustration: losing contacts after networking events because paper business cards end up forgotten in a drawer. After 25 years in industrial maintenance, I attended hundreds of conferences and trade shows. Every time, the same problem - exchanging paper cards, promising to "stay in touch," then never finding the card again. I looked at existing solutions. They all wanted to sell me a $50 plastic NFC card. But wait - my phone already has NFC built-in. Why do I need another piece of hardware? That's when I discovered Android's HCE (Host Card Emulation). Your phone can act as an NFC card natively. No plastic needed. So I built Cards Control: the first app that uses HCE to share your contact info with a simple tap. Add AI scanning for paper cards, unlimited profiles for your different roles, and a fair pricing model (no subscription trap), and you have an app that actually solves the problem. Launched December 2025. Solo founder. Bootstrapped. Built with Flutter, Firebase, and Claude Code
Cards-Control.app's answer:
No hardware required - Popl, Mobilo, and Linq want you to buy a $30-$80 plastic card. Cards Control uses your phone's native NFC. Zero hardware cost. No subscription trap - HiHello and Blinq charge $6-$15/month for premium features. We offer โฌ49/year or โฌ199 lifetime. Pay once, own it forever. True NFC emulation (HCE) - Most apps just generate QR codes. Cards Control turns your Android phone into an actual NFC card, like Google Pay but for your identity. All-in-one solution - Competitors make you choose: CamCard scans cards but doesn't share. Popl shares but doesn't scan. Cards Control does both, plus full NFC read/write. Unlimited profiles - Business, freelance, personal - switch instantly. Competitors charge extra for multiple profiles. Works offline - No internet? No problem. Your cards are always accessible. Privacy-first - Your data stays yours. We never sell your information. 20 languages - Not just English. Built for global networking.

My programming assignment, in general, is good, I got 81 out of 100, and I was planning to get more, but it is still I still want to work with your team, and looking forward to receiving good work from a great team. I received some notes about the PPT that it was very basic, but overall, I would really thank you for the quick response and actions from your side in a perfect timeline :)
