AFD BankFinder

Just one sort code error or one digit wrong in a credit card number results in rejected transactions and declined direct debit or standing order payments.

BankFinder® uses sophisticated checks to prevent these errors and highlight potential fraud while speeding up data entry.

There is potential for error in any human typing of bank account details. Client bank data has to find its way onto our systems, and we need to be sure that it is accurate before processes of authorisation, entry to accounting systems and fund transfers take place.

The software is easily implemented on websites, in retail stores and call centres or on mobile devices. It’s valuable in many organisations including utilities, local government and charities.

BankFinder helps you deliver better customer service, sound financial administration, improved accuracy, lower rejection rates and lower costs.

We use AFD's BankFinder solution online as part of the new member onboarding process. There are a number of reasons people drop out of the sign-up process which we monitor; luckily the bank validation software ensures payment details are not one of them.

AFD Software is an Authorised Distributor of the Extended Industry Sort Code Directory (EISCD), the data used to check the validity of bank sort codes.

AFD BankFinder is accredited by the Pay.UK Sort Code Validation Accreditation Scheme. This is an independent payment industry assurance of the data quality and integrity of BankFinder. Pay.UK operate the UK retail payments operations including BACS, Faster Payments and Cheques.

BankFinder data is updated weekly to meet payment industry best practice. Any BACS emergency updates are processed by AFD and distributed without charge within 24 hours.

Applying all updates is essential to proper verification and checking of bank data.

Updates include comprehensive data for all banks in the UK and Eire banking system. This includes postal address, FPS (Faster Payments Service), BACS (Bankers Automated Clearing Service), CHAPS (Clearing Houses Automated Payment System) and C&CCC (Cheque and Credit Clearing Company).

Type a sort code and BankFinder will provide full bank details. Then type the account number and BankFinder will “normalise” it and check that it relates to the bank details. Type in credit or debit card details and BankFinder will check the number is valid and return the card type for confirmation. For Building Society credit accounts requiring a Roll Number, BankFinder will prompt for and validate that too.

BankFinder will work out of the box with any Windows application. It also has a fully featured, easy to use Windows API. A UNIX version of BankFinder is available along with the versions for mobile devices and for use with Internet websites.
