Velocity Controls and Fraud Filters

What are Velocity Controls and Fraud Filters and how to configure them

Velocity Controls

Velocity controls are settings that determine transaction thresholds for a particular Merchant. This allows a merchant to monitor transaction flow, transactions by IP address, card number, and amount, right down to the hour.

1. Select the Administration tab
2. Select Terminals
3. Select the terminal you want to configure
4. Choose Velocity Controls
5. Choose the appropriate Limit, Duration and Action for your needs
6. Click “Update”

Settings Definitions

There are seven configurable settings:

• Maximum Sale $ - Set this to determine the maximum dollar amount to allow for each transaction.
• Minimum Sale $ - Set this to determine the minimum dollar amount to allow for each transaction.
• Maximum $ of Transactions - Set the maximum dollar amount for approved, or all, transactions within a specified time period (from 1 hour, up to 7 days) and whether to decline (transactions are not sent for authorization), or not.
• Maximum # of Transactions - Set the maximum number of approved, or all, transactions within a specified time period (from 1 hour, up to 7 days) and whether to decline (transactions are not sent out for authorization), or not.  
• Maximum $ Amount per Card/Check No. - Set the maximum dollar amount allowed per card or check number* per specified time period (up to 24 hours or up to 7 days) and whether to decline (transactions are not sent out for authorization) or not. This calculation is based upon approved transactions only.  Transactions that are not approved are not included in the calculation for maximum $ Amount per card/check no.

• Maximum # Transactions per Card/Check No. - Set the maximum number of transactions per card or check number* per specified time period (up to 24 hours or up to 7 days) and whether to decline (transactions are not sent out for authorization) or not.  This calculation is based upon approved transactions only.  Transactions that are not approved are not included in the calculation for maximum # transactions per card/check no.

• Maximum # Transactions per IP - Set the maximum number of transactions allowed per individual IP address per specified time period (up to 24 hours or up to 7 days) and whether to decline or not.  This calculation is based upon approved transactions only.  Transactions that are not approved are not included in the calculation for maximum # transactions per IP.

Manage Your List of Fraud Filters

Under the Fraud Filters section, Fraud Filters can be managed a few different ways:

• View the list by All, Negative, or Positive Fraud Filters
• Download the list into CSV to manually update
• Upload your own list from a CSV file, see below:

CSV File Format

• P,Customer Reference,BG
• P,Card Number,4111111111111111
• N,IP Address,1.2.3.4
• N,Customer Reference,BA
• N,Email,mick@fraud.com
• N,Address,123 Crook Street
• N,Country,UK
• N,Card Number,5454545454545454

NOTE: If you create a CSV file for upload, it will overwrite any existing Fraud Filters that are in place.

Creating Wildcards for Fraud Filters

The following transaction fields come into play when detecting fraudulent transactions. The table below indicates those fields and whether or not wildcards are available when creating your filters

'*' - matches any character(s) in the expression and can be anywhere in the string. To use the '*' symbol literally escape it with '\'. 

Examples:

• *abc - matches '123abc', and does not match '123abc123'
• abc* - matches 'abc*', and does not match '123abc123'
• a*c - matches 'abc', and does not match 'cbc'
• a\*c - matches 'a*c', and does not match 'abc'
