1033 Dodd-Frank

1033 Dodd-Frank is an abbreviation and refers to Section 1033 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Section 1033 grants consumers the right to access their own financial information held by banks and other financial institutions. 

Section 1033 is a step forward to creating empowered consumers with greater control of their financial data and allowing them to access and share their financial information electronically. This has great implications for supporting innovation and competition in the financial services sector without compromising on the importance of consumer consent and data security.


ACH (Automated Clearing House) is the network for electronic financial transactions in the US. The ACH Network facilitates funds transfer between banks and financial institutions, such as direct deposits, consumer payments, B2B payments, and more. ACH payments get processed in batches and are known for their efficiency, reliability, and cost-effectiveness. The Clearing House runs the ACH Network, and Nacha is its governing body. 

A2A Payments

A2A (Account-to-Account) Payments are direct funds transfers from one bank account to another. A2A payments occur directly between the payer and the payee; no middlemen are involved. This payment type is often utilized for various transactions, including P2P (Person-to-Person) transfers, bill payments, and B2B transactions. A2A Payments leverage the ACH Network to process fund transfers and have rapidly grown in popularity in the US.

Account Verification

The primary goal of account verification is to ensure that the individual claiming ownership of an account is the legitimate account holder. Account verification is crucial in ensuring merchants comply with KYC and AML regulations. In the context of Open Banking, Account verification often uses consumer-permissioned bank data accessed via API to quickly and accurately onboard consumers.


AML (Anti Money Laundering) are the regulations, policies, and standards set by law to prevent and detect money made through illegal means passing as legitimate. AML efforts also combat the financing of terrorism. KYC is an important part of AML efforts that all merchants and financial institutions must adhere to.


An Application Programming Interface (API) is a set of defined protocols, standards, and tools that allow third-party developers to access and interact with consumer-permissioned financial data from banks to provide and build personalized financial products and services.

FDATA promotes competition, innovation, and consumer choice in the financial services industry, particularly in the context of Open Banking and Open Finance.

Friendly Fraud

Friendly fraud, or chargeback fraud, occurs when a consumer purchases a product using a card and later disputes the charge with their card issuer, claiming the transaction was unauthorized or fraudulent. Despite the term "friendly," it is not a genuinely amicable act but rather a misrepresentation of the transaction, whether intentional or unintentional, to effectively steal from a merchant.

Guaranteed Payments

Guaranteed Payments assure the secure and certain transfer of funds, minimizing the risk of payment failures and eliminating the risk of chargebacks. This provides the payer and payee confidence that the transaction will be completed successfully.

Identity Verification is important for fulfilling KYC requirements and fighting against fraud and other malicious actors. Identity Verification involves validating consumer information, including personal details, biometric information, and more.

Real-Time Payments are done on Real-Time rails such as the RTP Network provided by The Clearing House and FedNow, released July 2023.


RfP (Request for Payment) is typically a formal document or communication to request payment from another party. The RfP outlines the payment request details, including the amount owed, the due date, and instructions on how to make the payment.


SCA (Strong Customer Authentication) is a regulatory requirement in Europe requiring that checkout flows verify identity through two of the three following ways: knowledge (such as a password), possession (such as a mobile phone number), and inherence (such as a fingerprint or face ID).
