Group Config

BACS and Faster Payments group config settings are shown below.

Service User Number (SUN)

A SUN is a 6 digit number used by BACS to identify organisations when submitting payments. NB. Your company could have more than 1 SUN.

Payment Signing Method

This determines how a submission linked to this group will be signed. The options are:

HSM - the HSM holds details of a security certificate issued by your bank.

Smart Card - use a bank issued smartcard to sign a submission. This is BACS specific and the card must be registered with BACS. The smart card is usually allocated to a single user to sign a submission.

HSM Certificate

This dropdown is shown if the signing method is “HSM” allowing you to select the HSM certificate used for signing.

Individual Payment Limit

The amount of an individual payment item this group can process when creating a new submission. Set to a default of £0 means there is no limit for an individual item up to the BACS and Faster Payment limits of £20 million and £250,000 respectively.

Submission Payment Limit

The maximum amount of an entire submission which this group can create. Set to a default of £0 means there is no limit.

Delete Payment Data

When this option is selected, the imported payment data is deleted from the database after the payments have been submitted. While it may be considered more secure to not have your data stored permanently the downside is that searching for previous submissions won’t be as effective.

HSM PIN Required

A group can be configured so an HSM PIN needs to be entered as part of the signing process. Each user has their own HSM PIN which needs to be configured by the paygate administrator.
