DETAILED DESCRIPTION OF THE INVENTION
The main features of this Digital Coin with Thirty Thousand Cents are as below :
1) Simple QR code generated for user making offline payment. This is because any offline balance in the user handset is represented by just one Coin with the said value.
2) The QR code generated is of high security because this code having a string of 6 Digit Random Generated Number (6D) embedded inside this QR code, where only the Center know if this 6D is genuine or not.
3) During user offline, the user can perform up to 100 times offline payment. After this the user handset must connect to the internet and update this Digital Wallet software. Then he/she can do another 100 times offline payment again.
4) Can be used for user with handset only, and do not have internet connection or even an active SIM card inside his/her handset.
5) One Coin code for one user and this Coin can represent any value. For example if Azahar need to pay in hard currency exact RM25.35 to Lina, he need to get one RM20.00 note, one RM5 note, one 30₡ coin and one 5₡ coin. But with this Digital Coin with Thirty Thousand Cents system, Azahar just need to key in 25.35 and press pay. This mean the Digital Wallet manufacturer just need to create less Coin to fulfill the market need. This save a vast amount of cost and time for the manufacturer.
6) Very easy to make offline payment. The user key in the amount and press pay. A QR code generated for the receiver to scan. After receiver scanned this QR code, the Center will process this code and notify the receiver this amount has been received. Then this transaction is completed.
7) No lose of money if the QR code been generated but receiver not scan this QR code to receive this payment. For example, the sender key in an amount and press pay, a QR code generated, at the same time the sender offline balance is reduced with the said amount been deducted. Yet, due to some unforeseen reason, like out of sudden the receiver handset can’t connect to the internet, so can’t scan this QR code to receive this payment. This mean the transaction has been failed.
But, as long as the sender can find a WIFI source and connect his/her handset to the internet and do update of his/her Digital Wallet software, the Center will know which sender offline transaction is failed, and this amount will refund back to the sender right away by top up this amount into the user offline balance.
