Tapping Application Payment System (TAPS)

Problem Statement

In the past decade, Bank Negara Malaysia has been pushing initiatives to adopt cashless economy through provision of credit and debit cards. But, Malaysia's cash usage still remains high at 6% per GDP. This is mainly due to high cost and inconvenience of providing card service payment for small business such as highly mobile roadside stalls. High cash transaction rate will lead to theft of cash, high daily banking activities and can lead to falsified accounting records that allow unauthorized payment and avoid taxes. In this modern world, everyone has a mobile device carry with them. Therefore, TAPS which is a device-to-device tap technology that takes the card payment machine out from the system is proposed.

Aims
To develop a safe, effective and convenience cashless transaction payment system through device tapping for small business such as roadside stalls, mamak restaurants and street markets.

Objective
- To implement transaction through simply act of tapping card by using the technology of Near Field Communication
- To integrate Low Power Wide Area Network into the system to reduce cost and complexity of using mobile wallet.
- To record the transaction happens in the network and save in database or using blockchain technology.
- To develop a safe environment to perform transaction by implementing tokenization.

Deliverables
- Users able to perform transaction by simple act of tapping each other device.

- Users able to check for balance.

- Users can login to the system.

- Users can top up money into the system through Paypal or other instance.

- Users able to view transaction history.

- Users able to register themselves into the system

i) Enable users to perform transactions by tapping two devices together through Near Field Communication (NFC)
- Device that has NFC, by inserting amount, the transaction can be made through tapping each other device using NFC.
- Save transaction through blockchain.
ii) Enable users to login into the system.
- Users will key in their registered username and password.
iii) Enable users to register themselves into the system.
- Users will register themselves into the system by registering through username and password
- username will be unique.
- password must be above 6 digit ( must be mix of alphabet and number)
- registered user will be saved into database ( not sure about this, can be using blockchain ? Please answer)
iv) Enable users to top up money into the system through Paypal or other instance.
- Top up money (IN RM ONLY) through PAYPAL . ( Please provide with steps)
v) Enable users to view transaction history
- The transaction made through NFC and saved in blockchain can be viewed.
- Able to categorized by DAY. For example transaction made in (12/8 to 19/8 only, by default show latest 30 transaction.)
vi) Enable users to check for balance.
- Remaining balance can be check IN RM ONLY.
vii) Enable users to set transaction limit.
- Allow users to set transaction limit. For example, highest transaction can be made everytime is lower than RM 100. Must key in PASSWORD again to change.
viii) Utilize tokenization to develop a safe environment to perform transaction.
- Secure transaction with tokenization, the transaction must be using tokenization and able to integrate with blockchain.
ix) Record and save the transaction happens in the network by using blockchain technology
- SAVE everything using blockchain (everything include transaction, username and password.
