Information on the character of merchant fraud can be seen in our articles on the fraud protection aspect of payment gateway selection.
Merchant fraud protection systems are generally included in payment gateway software products. They are based on many norms for observing each merchant’s transaction processing activity. The coming flow of transactions is scanned and checked against this standard on some regular generally daily. Or monthly basis. If some distractions take place. They are straight away flagged. Underlying merchants or transactions can be seen. And any compulsory measures can be taken as fruitful as possible.
Let us now look into the basic criteria. Giving the conceptual basis for merchant fraud protection tools.
Some standards are observed on daily basis as well as on a quarterly basis. For example, a huge transaction amount is a standard inspected on daily basis only. While majorly processing volume can be inspected both daily and monthly.
For every specific business. Relying on its nature, a limit is, usually, made for one or more norms. If the limit is surpassed, the incident is inspected, and, if necessary, particular measures are taken.

The maximum permitted processing volumes

Usual transaction volume. As well as transaction count, are inspected. At the very basic level. The highest and lowest transaction (ticket) costs, which a merchant specified in the merchant application, are observed. Particular deviations from these standards might show some sort of merchant fraud.

The maximum shift from averages

Generally, most businesses come after the same processing patterns in day-to-day style or month to month with no departure from average. If any particular diversions seen from average are registered. They are declared as signals for checking the particular case behind the deviation. Generally, granted deviations amount is up to near about 5-10 %. If this limit is significantly surpassed. It may raise the impression. Deviation restriction should be seen in an average in every transaction amount. Average daily transaction count. And average daily (monthly) processing volume. Basically, a 60-day window is used for daily averages and a 12-month window for monthly ones.

For certain sorts of businesses deviations from average are typical (for example. Seasonal or instigated by the sale of some highly-demanded product). So the standard is not always a conclusive one. But in certain cases, it can be pleasant.

Fraud suspects

One of the signals. Which may cause doubt. Is a huge amount of micro-transactions. Which are generally below $1. In some scenarios, a huge number of even-amount transactions can also be known as a sign of fraud. For example, if a merchant runs a retail business and the transaction amount basically includes taxes. An even-amount transaction is sort of an exception than a rule. While for e-commerce businesses even-amount transactions are much more common.


Duplicates can either mean actual fraud or you can say just a human error. Duplicates can be diagnosed according to many criteria.

For a few businesses, too many transactions with a similar amount are not typical. So in the case when they might define fraud. On the other hand, some businesses give them a restricted amount of products\subscriptions. And for these businesses many transactions with the duplicate amount are ordinary.
Another same-related criterion is the number of transactions linked with the same card number. If the number is too much, it may be a symptom of fraud.
In a few cases a huge number of transactions with a similar amount paid using the same card during a short amount of time, for instance. We can say a day may also mean fraudulent activity.

Transaction variety

Oddly, a huge percentage of transactions of a definite category in the overall transaction volume is one more representative standard. If the maximum permitted percentage of credits, refunds, verifications rejects. ACH reverse backs or chargebacks is above the limit. It may be a signal of merchant fraud have been taken place.

Entry mode

If we talk about the card entry mode there are typically three basic card transaction groups: swiped, keyed, and CNP. If a few sorts of entry mode is controlling a business. An immediate boost in the number of transactions with one more entry mode may define as fraud.

Off-hours transactions

Some transactions are generally submitted during shop hours which is generally before 8 am or after 8 pm.

For a few businesses, after-hours processing is granted, but which is not usual in a large number of transactions capitulating after hours may be a mark of potential fraud.
If transaction density is, usually. Repeatedly scattered all across the merchant’s working schedule (for example, majorly transactions take place in the morning). Unexpected shifts in this distribution may also be considered doubtful and, possibly, specify merchant fraud.

Merchant inactivity period

Some merchants stop processing transactions but do not close their merchant accounts. Such merchant accounts can, potentially, be used by fraudsters. Consequently, the number of days during. Which there is no activity on the account should be monitored, in order to prevent potential fraud due to the merchant’s lack of attention.
The absence of activity does not signify fraud, but rather. Specifies that the merchant is not in the use of the account.
