Payments Transfers via Bank Account Data
Why Payments Transfers via Bank Account Data are More Advantageous Under the New Regulation?
To justify our recommendation, let’s first clarify the differences between bank account details, Pix key, and Pix payments:Bank Account Details
These are the traditional details associated with a bank account, such as bank name, account number, and branch code. In Brazil, these details are used for transactions where the specific bank and account need to be specified directly. These are unique and non-transferable, similar to an address, and cannot be moved to another financial institution.Pix Key
The Pix key functions as a nickname for bank account details, simplifying the process of receiving payments via the Pix system. The Pix key can be an identifier such as a CPF (tax ID), email, phone number, or a randomly generated key. It simplifies the process of receiving payments, eliminating the need to enter all bank account details. However, since the Pix key can be transferred between banks and accounts at any time, this flexibility requires revalidation, which may lead to transaction rejections if data mismatches occur.Payment via Pix
Pix is Brazil’s instant payment system, enabling transfers in just seconds, 24/7, even on holidays. Payments can be made in two ways:With a Pix Key
The payment is directed to the Pix key registered by the user, such as CPF or email.With Bank Account Details
The payment uses the user’s traditional bank account information (branch and account number) but is still processed by the Pix system, maintaining the speed and immediacy of the payment.New Regulation and Compliance
With Ordinance 615, the Ministry of Finance mandates that, to make deposits and receive prizes, users’ accounts must:- Be registered with an institution authorized by the Central Bank of Brazil (BACEN)
- Be linked to all transactions
Pix Key Limitations
Though convenient, the Pix key presents challenges for high-volume transactions:Limit on DICT Queries
Frequent queries to the Directory of Transactional Account Identifiers (DICT) to validate Pix keys can reach a daily limit, leading to temporary blocks.Risk of Inconsistency
When users change their Pix key to another bank, data mismatches may occur, impacting the continuity and security of payments.Advantages of Using Bank Account Details in Pix Payments
With WEpayments, when making payments directly to registered bank account details, the institution validation occurs at the time the request is created. This way, the user is immediately informed if they need to review their registered account, eliminating potential rejections and ensuring a higher conversion rate and a better user experience in the long term.Reduced Rejections
Since bank account details cannot be transferred between banks, there’s no need for revalidation with each payment. This lowers the likelihood of transaction failures and rejections.Regulatory Compliance
By using bank account details with the Pix system, the payment aligns more closely with regulations, as the registered account is verified and fixed.Conclusion
With new regulatory requirements and Pix key limitations, we recommend using payments via bank account details through the Pix system. This approach maintains the speed and reliability of Pix while providing enhanced security and regulatory compliance, delivering a stable and reliable experience for the user.Comparison Table
