Project Goal: The project has multiple goals:
- Сreating an application for saving an account (wallet) on an NFC card. It is a cheaper alternative to Ledger and more reliable than writing on paper.
- Creation of infrastructure for the popularization of the TRON cryptocurrency (Including among those who have not previously used cryptocurrency). NFC cards can be used as gift cards or as an alternative to selling crypto through exchanges.
Project Info: soon
Project Website: soon
Project Test Instructions: soon
Project Details:
The project consists of two applications.
- The first application is a web application that allows you to read NFC cards. It works in the browser and does not require installation (Only for Android devices: smartphones, tablets or terminals).
- The second application allows you to quickly create NFC cards.
Both applications run on the TRON blockchain.
This is an example of NFC card design:
This is a mini demo video (good quality video will come later):

Project Milestones:
- Create web app for reading NFC cards
- Create app for create NFC cards

Good evening. The private key will be stored in encrypted form on the NFC card. To access the wallet, the user will have to enter a password.
The password is set when the wallet is created (optional).

I like your project because it works on any device, it doesn’t need any special app . With any web browser you’re good to go
Congratulations in advance…

Welcome team, just want to clear some doubts, the NFC card will serve like an ATM card linked to your wallet address and a person can person transactions with the card without necessary having to open the wallet in the first place.
Please correct me if i am wrong

Hello. No. The card serves as the key to the wallet. The private key is stored on the card in encrypted form.
However, it is possible to develop software for the ATM terminal. Not in this hackathon.

TronWeb api is used to create a wallet. At the time of creating the wallet, you can view the seedphrase. However, the seedphrase is not saved in the app or anywhere other than the NFC card.
The application code will be fully open source by the end of the hackathon.

Oh great, okay
Thanks for the clarification.
All the best
Oh ok, i was proposing something like this but my idea was flawed in many ways, cant wait to see how u go about yours.
Mine was to mint the seed phrase as NFT but i have found out its not good enough as the NFT will be public and therefore vulnerable.
I want to see how you approach works
We never can tell
Idea on idea can turn out to build a perfect project.

How do you address regulatory compliance, such as KYC and AML requirements, for users of the NFC wallet cards?
