INDEX

Many businesses that operate e-commerce sites and online services may be worried that they want to introduce a career payment, but they don't know how it works, costs, and risks.

While the introduction of Carrier payment can be expected to increase purchase rates and reduce the risk of non-collection, there are also points to be aware of.

In this article, we will explain how Career payment works, the introduction process, advantages and disadvantages, limits, and precautions.

What is a career payment?

Career payment_Illustration.pngCarrier payment is a payment method of paying for goods and services by combining them with your monthly mobile phone bill (communication bill). It is mainly used for in-app purchases, online shopping, e-books, etc., and is provided by major carriers such as NTT DoCoMo, KDDI (au), and SoftBank. The main feature is that you only need simple authentication such as ID and password (or biometrics) to complete payment, so you don't need to enter your credit card information.

How payment works

Carrier payment is carried out between three parties: "user", "operator", and "telecommunications carrier", and the process is completed in the following flow.

  1. When the user purchases a product, they select "Carrier payment" and authenticate with a PIN or other information.
  2. Each telecommunications carrier temporarily repays the price and deposits it into the operator.
  3. The user will add it to the mobile phone bill and payment the payment to the telecommunications carrier.

In this way, since the carrier repays the price, it can be said that it is easy for businesses to reduce the risk of unrecovered.

There are two ways to introduce carrier payment: "direct contract with each telecommunications carrier" and "using a payment processing company company (PSP)".

Both methods have their own characteristics, and the best option depends on the scale of deployment and operational structure.

Features: There are no brokerage costs, so you may have lower fees than using a payment processing company company.

Note: Each carrier requires screening and system development, which tends to bloat the number of man-hours and management costs.

2. payment processing company Use the company

payment processing company is a way to contract with a company and introduce multiple carriers at once.

In addition, the market price of the monthly fee is about 0 yen to 15,000 yen, and it is mainly incurred every month as a system usage fee and management fee.

payment Fee Features and Comparison

Carrier payment 's payment fees are generally around a few percent to 10%, which is slightly higher than credit cards. This is because the cost structure includes risks due to the mechanism in which carriers make advance payments.

Let's proceed with the introduction with an emphasis not only on price but also on operational convenience and reliability.
