A code system for preventing fraud in trading and at the same time a safe payment method for business and consumer. The code system of the present invention ensures security and control for the contracting parties regarding the previously defined attributes of the goods and the payment including all decisional steps of the transactions as well as of the reverse transactions in case of complaint. The contracting parties act complementary, money and goods or money and services are never at the same time under control of one contracting party.

## Claims

### Claim 1

A system comprising:
a computer server coupled to a network for carrying data, the computer server having at least one central processing unit;
a memory coupled to the computer server and adapted to store a database;
a the server corresponding to a host and operably connected to the network to host data corresponding to online transactions, including a buyer account and a seller account;
one or more input/output communication terminals devices coupled to the network and configured to transmit and receive codes associated with the buyer account and the seller account at a financial institution,
wherein the memory coupled to the computer server has software instructions stored therein that, when executed by the at least one central processing unit, cause the at least one central processing unit to perform operations including:
randomly generating a directional electronic funds transfer key having a variable number of bits divided into two parts of variable length, a first part associated with a seller and forming a seller code and a second part associated with a buyer and forming a buyer code;
storing the directional electronic funds transfer key including the first part and the second part in the memory;
electronically transmitting the seller code of the directional electronic funds transfer key to the seller and the buyer code of the directional electronic funds transfer key to the buyer;
blocking a sum related to a specific transaction on the buyer account and a certain variable percentage of the sum as a deposit on the seller account when contracted by the seller and the buyer conjointly until the specific transaction is concluded;
when the buyer accepts goods or services provided by the seller:
receiving, from the buyer, a buyer input including the buyer code;
electronically transmitting the buyer code of the directional electronic funds transfer key from the buyer to the seller;
receiving, from the seller, a seller input;
determining that the seller has electronically provided, in the seller input, the directional electronic funds transfer key including both the seller code and the buyer code; and
in response to determining that the seller has electronically input the directional electronic funds transfer key, electronically transferring the sum to the seller account and electronically unblocking the certain variable percentage of the sum deposit;
when the buyer does not accept the goods or services provided by the seller:
returning the goods to the seller when goods were provided;
receiving seller confirmation that the returned goods correspond to the goods provided by the seller;
electronically transmitting the seller code of the directional electronic funds transfer key from the seller to the buyer;
determining that the buyer has electronically input the directional electronic funds transfer key including both the seller code and the buyer code; and in response to determining that the buyer has electronically input the directional electronic funds transfer key, electronically unblocking the sum and transferring the certain variable percentage of the sum deposit to the buyer account;
when the seller does not deliver the goods or services:
requesting the seller code be transmitted from the seller to the buyer;
electronically transmitting the seller code of the directional electronic funds transfer key from the seller to the buyer;
determining that the buyer has electronically input the directional electronic funds transfer key including both the seller code and the buyer code; and
in response to determining that the buyer has electronically input the directional electronic funds transfer key, electronically unblocking the sum and transferring the certain variable percentage of the sum deposit to the buyer account.

### Claim 2 (depends on 1)

The system of claim 1, wherein the system is further configured to maintain a reserve on funds in a buyer or seller account respectively so that in case of a complaint the funds remain reserved on the respective accounts.

### Claim 3 (depends on 1)

The system of claim 1, wherein the system is further configured to automatically transmit the seller code when the buyer and the seller confirm and not transmit the seller code if a party does not confirm.

### Claim 4 (depends on 1)

The system of claim 1, wherein the buyer and the seller include a plurality of vendors and a plurality of buyers.

### Claim 5 (depends on 1)

The system of claim 1, wherein the system is further configured to:
instantly transfer money in a pay-out process, whereby a money sender creates a key and the system transmits automatically a part of the key to a money recipient,
wherein after receiving the part of the key, the money recipient presents himself at a pay-out communication terminal connected to the system or uses an automated teller machine (ATM) having access to a storage containing the key, and
wherein after the input of the part of the key in the communication terminal, cash out takes place and the money can be paid out to the money recipient even when the money recipient has no bank account.

### Claim 6 (depends on 5)

The system of claim 5, wherein the system is configured to permit a user to create a key and configured to permit use of a code component in a pay-out process or for a cashless payment and for receiving change, when a sum due is less than a sum of the cashless payment paid for the sum due.

### Claim 7

A method comprising:
randomly generating a directional electronic funds transfer key having a variable number of bits divided into two part of variable length, a first part associated with a seller and forming a seller code and a second part associated with a buyer and forming a buyer code;
storing the directional electronic funds transfer key including the first part and the second part;
electronically transmitting the seller code of the directional electronic funds transfer key to the seller and the buyer code of the directional electronic funds transfer key to the buyer via respective input/output communication devices coupled to a network and configured to transmit and receive codes associated with a buyer account and a seller account at a financial institution;
blocking a sum related to a specific transaction on the buyer account and a deposit on the seller account when contracted by the seller and the buyer conjointly until the specific transaction is concluded;

when the buyer does not accept the good or services provided by the seller:
receiving seller confirmation that returned goods correspond to the goods provided by the seller;
electronically transmitting the seller code of the directional electronic funds transfer key from the seller to the buyer;
determining that the buyer has electronically input the directional electronic funds transfer key including both the seller code and the buyer code; and in response to determining that the buyer has electronically input the directional electronic funds transfer key, electronically unblocking the sum and transferring the deposit to the buyer account;
when the seller does not deliver the goods or services:
requesting the seller code be transmitted from the seller to the buyer;
electronically transmitting the seller code of the directional electronic funds transfer key from the seller to the buyer;
determining that the buyer has electronically input the directional electronic funds transfer key including both the seller code and the buyer code; and
