Inspiration
To make fintech accessible at all places at all times
What it does
It enables fintech transactions even without network connections. It works by near field communication technology between two devices. Two connected devices can either send or receive payment when connected .This connection is independent of internet. The transaction details are stored in both devices. As soon as one of the devices connects with the ENTAN wallet server ,the transaction details are shared and the money is transferred . This transfer of money is guaranteed as soon as one of the devices comes into contact with the server . Hence user's can reliably transfer money even without network
How we built it
It is a device in which NFC module in which the user's data is transmitted along with that a microprocessor capable of processing the transaction and creating a transaction ID .A flash memory capable of storing several transactions and the operating system data. A GSM module enables the device for connection to ENTAN wallet server along with that a Bluetooth module helps the track nearby active devices even when there is no communication with the ENTAN wallet even in the absence of internet and network connection .A O-LED display will be provided as a user interface
Challenges we ran into
Battery capacity and trying to reduce the size of the device
Accomplishments that we're proud of
Building a compactable device can fit in our pockets which enables offline transactions
What we learned
Learned about near field communication, server management
What's next for ENTAN
Building a better prototype for commercial production
