Develop software for a Castles V5 terminal for NFC tap to pay use case

I have software that is able to debit and to credit values to NFC Mifare classic 1k tags. The software is also able to generate reports for the transactions.

However, the apps work offline meaning data loss is possible if anything happens to the device.

I need to enhance the existing software to allow it to write to a MicroSD on the terminal and to broadcast the transactions to an online server via WiFi or GSM Sim card.
