Cases where your order may be cancelled

The number of cases has increased recently, so I would like to inform you again.

Our store uses Shopify, an e-commerce service from Canada. Shopify monitors all customer payments to ensure they are valid using a system called fraud detection. This is not to suspect you, but to protect your rights. Even if your personal information has not been leaked, it may have been leaked somewhere, so we check to make sure that payments are not made without your knowledge.

This detection system has become a lifeline for the store. We call the fraudulent use of credit cards "digital shoplifting," and when it occurs, not only are the goods stolen, but the store must also compensate the cardholder for the loss .

Let's say you're selling a product with a purchase price of 40,000 yen and a selling price of 50,000 yen. If this product is digitally shoplifted, your loss will be 40,000 yen.
The profit from selling one is 10,000 yen (actually it's less), which means you would have to sell four or more to make up for the loss of one digital shoplifting.

Now, when a store suspects fraudulent use, they are forced to decide whether to take the risk of huge losses or to make a sale anyway. In that case, they investigate whether the purchase was actually made by the customer based on the fragmented information provided by the payment company (just to be clear, we are only given the last four digits of the credit card number, so it is impossible for us to fraudulently use this information ) and whether the purchase was actually made by the customer.

If, after investigation, we find something suspicious, or if we decide to cancel the order just to be on the safe side, we will cancel the order. In our case, the criteria for deciding to cancel are a high amount of payment and the customer's information is intentionally concealed.

This is because high-value payments are often for products that are easy to resell. 100% of fraudulent use is also committed for such products that are easy to resell.
There are two cases where a person's information is intentionally concealed: hiding the source of access, and using an email address that anyone can easily obtain.

In most cases, the method of concealing the source of access is to use a proxy server. There are also reasons for using a proxy, such as when you are accessing from a workplace and do not want your administrator to know about it, or when you want to reduce data volume.

Speaking of email addresses that anyone can get, anyone can get a gmail address, but there are surprisingly few cases of fraudulent users using gmail, and I think that if you use it in a suspicious way, you will be banned. And there is an email address that most fraudulent users use.

If someone who happens to be using that email address makes a purchase with their own card, we have to cancel the purchase because, although 90% of the time, the 10% is too dark . It's not the customer's fault, it's the person who uses the card fraudulently who is at fault.

Conversely, there are also cases where the detection system judges the transaction as black but the transaction turns out to be white. This is a payment made through an external payment service. To be specific, this would be Amazon Pay or Paidy. In this case, the payment service usually verifies the user's identity, so our store processes the transaction as white (although of course, the transaction may turn out to be black).

So, if your purchases are cancelled or you receive a lot of confirmations not only at our store but also at other stores, it may be that your access method or the information you provide is similar to that of someone who is using the service fraudulently. So, it may be a good idea to try changing that.

In addition, our store accepts prepayment by bank transfer as a 100% shipping payment method. If you absolutely must do so, please let us know.
We will also gradually increase payment methods that do not require credit cards, such as deferred payment.

*The factors for judgment introduced here are only a small part of the various information provided. Even if someone who is trying to do something bad uses this to disguise their information, there is a very high possibility that they will be judged as being suspicious. In addition, the process of detecting fraudulent use and reporting is carried out very systematically. Please be very careful not to become involved in fraudulent use without thinking. There are part-time jobs where you only forward products, and part-time jobs where you only receive products. Our store also reports cases that are clearly suspicious to the police.
