Thales Case Study: Secure Payment Submission
BACS (Bankers Automated Clearing System), the UK ACH service, is one of the largest and most successful money transfer organisations worldwide. Its Direct Debit and Direct Credit services process over 60m payment items in a busy day, on behalf of over 100,000 UK businesses. The infrastructure of BACSTEL is now aging rapidly, proving more expensive than more modern alternatives to operate and lacking the flexibility to support new, innovative services. The smartcard is used to digitally sign all payment instructions, tying them to the signer and ensuring that they cannot be accidentally or deliberately altered. Each bank has the flexibility to select its own Public Key Infrastructure (PKI) for the issuing of the digital certificates used on this card.
