Can you please clarify what work was achieved in Season 4 hackathon?

Here is your Season 3 submission where you said that this USDT functionality was already previously completed: TRON POS - HostingGift Cards in Web3 | Devpost

Hi fulldecent.

Thanks for taking the time to review the project and follow up on the progress.

On Hackathon season 3 the main idea was to use TRON transactions as a way to implement store gift cards, I realized it has many disadvantages such as having to use and store private keys in the application, and using additional transactions to track the paid value. Only USDT acceptance was there but not USDD, I got as a suggestion from users that it would be good to include USDD as TRON was been promoted in several Caribean islands.

Season 4 main feature is to integrate to Square and Sumup by implementing their SDK for transaction processing and API to reporting transactions. The advantage of integrating to Square is that the TRON transactions can be reported to Square as other payments and tracked in the Square back end for easy reconciliation, it opens new possibilities for accepting credit/debit and TRON payments in a single application and to integrate to Square gift cards.

Square is a very popular product with 10 million downloads in their Android application itself and available in 6 contries, and they have a powerful gift card program, having Square and TRON integrated in the same application will allow us to generate Square Gift cards as NFT, include the card PIN as encrypted QRcode and have it decrypted at the application when redeeming or online by the owner. (this is a future implementation) so it merges traditional gift cards with NFT and TRON. This will enable a customer to buy a NFT gift card using TRON stable coins, have the funds deposited in the store owner wallet and redeem as normal Square Gift Cards at the store.

Square added this week soft POS feature for android, allowing to accept contactless payments for credit/debit without the need of a bluetooth dongle. This will make it more accesible for small merchants.

Sumup is expanding their gift card program and is available in 34 countries

Changes in this version:

  • Added USDD payments
  • Added Square and Sumup Integration

Future enhancements:

  • Integrate Square Gift Cards and NFT such that consumers can buy them with TRON stable coins
  • Complete the integration to report TRON transactions as other payments in Square back end.

I re-used some previous comments , let me know if this convers your question.
regards,
Juan
