USSD technology uses online processing to ensure the security of this system. In these codes, information is exchanged as a code and with complex algorithms. USSD is a session-based messaging technology that has a session duration of 20 seconds. Disables the code if it does not receive a response from the user. USSD code modules include the following:

The Magic Behind USSD Codes

برای برنامه نویسی کدهای USSD موارد کلیدی وجود دارد که از جمله آن اشنایی با برنامه نویسی، عبارات شرطی، عبارات سوئیچ وغیره می باشد. یکی از مواردی که شما باید دقت کنید این است که کدهای USSD به زبان های مختلفی صحبت می کنند یعنی رشته ها را با اسم های مختلفی ارسال می کند. برای این آموزش قصد داریم موارد زیر را به عنوان پارامترهای درخواست نمونه خود تطبیق دهیم.

All responses (data entered by the user via mobile phone) are separated by * and each response entered by the user results in an existing string. So for php you have to have the Explode () function.

How to Program USSD Codes

A very important point to know in USSD is the use of the keywords CON and End.

The CON keyword is used when referring to a persistent request. For example, when you expect a user to enter a response.

END برای خاتمه جلسه USSD استفاده می شود. هنگامی که این مورد را در ابتدای متن خود اضافه می کنید ، به ارائه دهنده می گویید که جلسه پایان یافته است و به این ترتیب به کاربر پس از آن یک صندوق ورودی داده نمی شود بلکه یک «خروجی» یا «خروج» داده خواهد شد.

Below is an example of PHP code There is:

<?php

#We obtain the data which is contained in the post url on our server.

 

$text=$_GET[‘USSD_STRING’];

$phonenumber=$_GET[‘MSISDN’];

#we explode the text using the separator ‘*’ which will give us an array.

$serviceCode=$_GET[‘serviceCode’];

$level = explode(“*”, $text);

//check to see of the text variable has data to avoid errors.

if (isset($text)) {

if ( $text == “” ) {

$response=”CON Welcome to the registration portal.\nPlease enter you full name”;

}

if(isset($level[0]) && $level[0]!=”” && !isset($level[1])){

$response=”CON Hi “.$level[0].”, enter your ward name”;

 

}

else if(isset($level[1]) && $level[1]!=”” && !isset($level[2])){

$response=”CON Please enter you national ID number\n”;

}

else if(isset($level[2]) && $level[2]!=”” && !isset($level[3])){

//Save data to database

$data=array(

‘electoral_ward’ => $level[2],

‘phonenumber’=>$phonenumber,

‘fullname’ =>$level[1],

//Insert the values into the db SOMEWHERE HERE!!

‘national_id’=>$level[3]

);

We end the session using the keyword END.

$response=”END Thank you “.$level[1].” for registering.\nWe will keep you updated”;

}

 

Also note that we echo the response for every successful request.

header(‘Content-type: text/plain’);

echo $response;

 

}

?>

Now it's time to test the code to see if it works or not.

For example, you can say that there is a charge purchase on your menu and you decide to buy a charge. One way that can get the job done faster is to put the charge purchase number next to the original code and get your charge.

It is possible to have the services of these companies on your site. You can use these services if you decide to create and expand your activity on the site.

Central Bank Performance Regarding USSD

One of the issues about USSD The central gatekeeper has done that in the ninety-third solar year, he received a commission for taking inventory, using command codes to thus reduce this type of transaction. In the year 1994, it stopped the conditions for buying and receiving balance for payment companies, and approved a ceiling of 200,000 Tomans for payments, so that all banking is done through the bank and only in very limited conditions of codes and services. Use USSD.

But a year later, a system was introduced by the central bank called Payvand. Through this system, telephone numbers and card numbers were connected to increase the need to enter the exchange card number and increase the security of bank accounts. Then, in the year 96, with the announcement of the National Bank, it became possible to pay public bills from this service, and other transactions were eliminated.

With this kind of central bank approach, businesses are based  USSD And the operators were created to confront and protest. The group claimed that the central bank's decision was sudden and had damaged their newly established businesses. But the reality was that the central bank had created and implemented its security measures about five years ago to create more security.

 The Introduction of USSD Technology In The World of Payments

Perhaps it can be said that in the current situation, operators and companies that operate with them as a subsidiary must break their resistance. Because today this type of technology, which has insufficient security, is naturally eliminated and safer services are provided.

The presence of newer technologies, such as Google Pay electronic payment, is expanding and developing today due to their quality. These types of services have a variety of services for their users and make good use of NFC technology.

The important point is that technologies, no matter how secure they are, can cause a lot of problems if they are not used properly and their use is unprincipled. For some time now, various organizations have been proposing the creation of e-wallet services. But the fact is that while the service USSD It has such problems that it has not been able to provide the necessary security for Iranian users. Is there a necessary platform to create such technology?

How And Conditions To Receive The Code USSD

Among the conditions that a site can code USSD The following can be mentioned:

One of the most important conditions is that the applicant's website has received the electronic credit symbol. Also, the group that manages the site should not have a bad record in the FATA police. On the other hand, having bad accounts with banks such as Melli and Mellat can be considered a negative advantage. Having SSL for the site is one of the requirements.

When a site requests this service, it must be active in one of the fields of virtual goods sales, domain sales, host sales, and payment gateways. Also, the site must have a history of three years and the site server must be created in Iran and the transactions made from this code must have a large number per day.

It takes ten to forty-five days for the port to be activated in this service. On the other hand, site administrators must send their site identification documents to the bank they are considering, and during this period, create programming facilities on the site and receive a tracking code from the bank. If the bank determines that the complete steps have not been completed, it can delete the gateway without notification.
