Payments on the Internet

Consider the example of the payment system when paying for purchases from an account in a bank.

The buyer connects via the Internet to the store’s Web server, forms a basket of goods and sends the invoice request to the store.

The store, in response to the request of the buyer, sends to him a certified digital signature (EDS) invoice in which it indicates:

name of the goods (service);

cost of goods (services);

store code;

time and date of the transaction.

From a civil point of view, this account is a proposal to conclude a contract (offer).

The buyer certifies with his EDS the bill presented to him and sends him back to the store, thereby making an acceptance. The contract is concluded with the signing of the invoice issued by the buyer. In the system, the account signed by the buyer becomes a check.

A check signed by two EDS (store and buyer) is sent by the store to the Bank for authorization.

The bank processes the signed check:

checks the availability of the store and the buyer in the system;

checks the digital signature of the buyer and the store;

checks the balance and limits of funds on the buyer’s account;

keeps a copy of the check in the database of the bank.

As a result of inspections, a permit or prohibition of payment is formed.

When authorizing payment:

the bank transfers funds from the buyer’s account to the store account;

the bank gives the store permission for the provision of services (goods delivery);

the store provides a service (releases the goods).

When a payment is prohibited:

the bank gives the store a refusal to make a payment;

the buyer is refused with a description of the reason.

The buyer fully controls the process of making a purchase. As a documentary confirmation of the completed transaction, each party will have signed electronic signature checks confirming the fact of the transaction and having legal force.

The holder of a bank credit card can register in advance in the CyberPlat payment system. Then, when making a purchase, he does not need to enter his credit card details, as was the case in the above scheme. When registering in the CyberPlat system, the buyer must indicate:

personal data (surname, name, patronymic, personal data, email address, mailing address, telephone number);

the parameters of your card (the name of the payment system to which the card belongs, the card number, the expiration date of the card, the name of the cardholder in the transcription as it appears on the card).
