I’d like some information on ACH tokenization


What is ACH Payment Tokenization?

ACH Payment Tokenization replaces sensitive account and routing number data with a random string of alpha-numeric data.  This data is called a reference token and is stored in lieu of full sensitive data. When the bank account is future billed, the token is sent. The ACH processor has the full account and routing number securely stored and using the matching token, processes the ACH transaction.   In contrast to the credit card processing world, ACH payment transactions were not mandated to be tokenized, rendering the sensitive data unreadable.ACH Tokenization While it’s definitely a best practice to protect sensitive data, it has only recently become a mandate from NACHA that security measures be put in place. ACH datapoints consist of a bank account number and routing #. The routing # identifies the consumer or businesses bank. The new NACHA mandate requires that these numbers be replaced with a reference token. The token is then stored with the customer data and when payment is collected or disbursed the reference token is sent as part of the transaction string. The ACH tokenization gateway has the full account and routing #’s vaulted.  

The Two Phases of the NACHA ACH Tokenization mandate

NACHA, the governing board that regulates the ACH network, came down with some new data security requirements. Those requirements are spread-out over two phases: Phase one covers originators and third parties with volumes greater than 6,000,000 transactions over year 2019. The effective date for phase one is June 30, 2021*. Phase two covers originators and third parties with volumes greater than 2,000,000 transactions over the year 2020. The effective date for phase one is June 30, 2022*. *The effective dates were extended by one year, essentially due to Covid. As part of NACHA’s governing authority, they regulate how transactional data must be safeguarded. The actual NACHA security requirement is neutral, meaning methods employed are not restricted to tokenization alone. However, given that tokenization is a commonplace best practice in the credit card world, and is what we provide to our clients, that is what our focus is on for  NACHA data security requirements solution.

Best ACH Tokenization Practices

Aside from the NACHA security requirement and having to comply, your organization should consider tokenizing sensitive bank account data simply because it’s the right thing to do. Would you want your checking account routing and account number being stored in a readable fashion on any company’s or organization’s computer system? Of course not. It only takes one breach – or a disgruntled employee with database access – to acquire and distribute that sensitive data. Taking proactive measures and complying with rules are your best options.

The Agile Payments Solutions

Agile Payments can provide to companies needing to render sensitive data unreadable is Tokenization. While any company that has been provided with an ACH processing solution from Agile Payments already has their ACH transactions tokenized, it’s the organizations and companies who typically have a direct ODFI relationship, which in turn usually places them in one of the top tiers of the NACHA mandate, that re those who require some kind of tokenization solution. Those organizations are usually accustomed to sending a NACHA formatted file to their ODFI for origination and subsequently are returned a similar file for rejected items. Those files contain sensitive data that needs to be rendered unreadable. We accomplish that via a tokenization solution, and the solution can communicate with your ODFI via system integration with that ODFI. Essentially the ACH tokenization gateway is connected with your bank, making it possible to use not only the tokenization solution, but a number of other tools that can assist with communication channels, reporting advantages, data collection methods and software API integration to name a few. ODFI Integration: Assuming your organization has decided to move forward with one of the Agile Payments tokenization solutions, we would have our integration team meet with your ODFI for integration specification details. We would then return you the details on the timing and the cost of the ODFI  ACH gateway integration. Communication Methods: When you utilize an Agile Payments ACH gateway solution, you then have the ability to communicate your ACH transactions a number of different ways.
  • File submission: Yes, you can still utilize a file submission, but not a NACHA formatted file. We would provide you with a proprietary file format that supports tokenization, and also many fields not available in a NACHA formatted file that assist a given organization with reporting and reconciliation. File submission is via a secure web portal and sFTP connection within that portal.
  • API: Two API’s are available (RESTful and SOAP) that allow any organization to integrate their software to the ACH gateway, thereby enabling tokenization. API integration has pretty much replaced most file specification users because of the automation that can be achieved, aside of the tokenization need.
  • Web Portal Submission and management: When using the ACH gateway for tokenization, you then also have the ability to use our web transaction portal (i.e., Virtual Terminal) to originate, receive reporting, search and view, schedule recurring schedules and reconcile settlements. The portal can be access by virtually an unlimited number of users within your organization, each with specific permissions. Again, tokenization is included.
  • Sensitive data collection tools: For some organizations, it’s not enough that sensitive data is not stored on their systems. Many don’t ever want to touch sensitive data when it’s collected. For those opportunities we have some javascript based tools that can be rendered on a webpage or mobile device, without leaving your URL, that transmit directly to the ACH gateway, never having the sensitive data ever touch your webserver. An immediate Post of the sensitive data is returned with a reference token for storage and future use.
We’re confident that we can provide your organization with an ACH tokenization solutions that exceed your requirements. The best ACH tokenization solutions should all start by understanding your specific needs.

Who is subject to the new data security requirements

The security requirement is relevant to originators that are not RDFI’s (banks), Third party senders and service providers who perform ACH processing functionality on behalf of an originator. All clients who have been provided ACH processing via Agile Payments are compliant because all modern tools and integration methods utilize tokenization. the focus of this particular page is geared more so for organizations who might have a direct ODFI relationship and are used to transmitting a NACHA file format, whereby they are likely storing sensitive bank account data. Further, it’s geared directly at those organizations who have ACH transaction volumes greater than 2 million annually, as mentioned above in the teo phases of the security requirement roll-out.

Below the Phase 1 or 2 volumes

if your organization is below the 2 million annual ACH origination volume number, NACHA doe not mandate that you comply with the new security requirement to render sensitive bank account data unreadable. However, they strongly suggest that you take a proactive approach and adopt the security requirement as a best practice.

Password Protected Databases

Restricting access to storage  systems that house sensitive data does not meet the NACHA security requirement. The data that is stored must still be rendered unreadable, and tokenizing that data is an acceptable solution.

Are you already PCI compliant?

Any organization that employs PCI data security standards to all platforms and storage systems are compliant for the new NACHA mandate. As with Agile Payments solutions, both credit card and ACH systems run on a PCI level one system and all sensitive data is rendered unreadable.
  • If we use you for ACH processing, aren’t the transactions already tokenized?
    Most likely, yes. If you are an integrated client, it’s up to you to properly integrate to tokenize the sensitive data.
  • Can we do this ourselves?
    That depends on what kind of IT team you have. There are some large organizations who rely on us for tokenization.
  • Are there volume breaks for cost?
    Yes, contact us and provide us with some recent processing history.
