These NACHA rules for merchants are designed to help secure your clients’ sensitive financial data. It also ensures secure and smooth transactions when it comes to online payments.

      If you are running a business and accept ACH payments, you will collect and store sensitive information belonging to your clients. This includes bank account and routing numbers, amongst others. As such, your business must comply with NACHA requirements.

      Below are the critical NACHA security rules for merchants:

      1. Secure Transmission and Safe Storage of Electronic Data

      According to NACHA, every time you send or store data, it must be encrypted. Using unencrypted emails or web forms could expose your clients’ details to scammers. To adhere to this rule, you can use tools such as Microsoft Office Message Encryption. Alternatively, for businesses that use cloud-based software to accept payments, confirm their database features robust encryption. This will ensure the safe storage of electronic data.

      1. Safe Storage of Hard Copy Documents

      If your business collects customer data in the form of hard copy, it is your responsibility to ensure it is stored safely. Invest in a quality safe that can secure your customers’ information. Additionally, you should restrict employee access to these documents.

      1. Validation of Routing Numbers

      NACHA requires before entering routing numbers into the ACH Network. You need to ensure they are valid. If you use a reputable ACH processing system, double-check to ensure their validation function fulfills this requirement. You can also validate routing numbers by checking its format or looking at it against a database of valid routing numbers.

      1. Verification of Client Identity

      Before proceeding with any transaction, NACHA rules require merchants to verify the identification of the customer. This is irrespective of whether the transaction has been authorized via phone or online. To confirm the customer’s identity, you can refer to forms received from the customer authorizing ACH payments. Alternatively, several third party sites offer customer verification. For businesses with a reliable payment processing system, the verification is built into the software to eliminate your responsibility for this task.

      1. Be Cautious about Fraud

      Always be vigilant when initiating ACH transactions. Ensure no fraud is involved. Counter check all duplicate and suspicious activity. Flag any signs of fraud. One of the benefits of having a payment processing system is that it will detect any fraudulent activities.

      1. Implement and Outline a Clear Security Policy

In the procedure, you should state measures you have undertaken in ensuring secure transmission, storage, and protection of confidential data. Don’t forget to include a section describing how you verify the identity of your clients.
