Pix via QR Code: differences between static and dynamic codes

What is static code and in what everyday situations is its use recommended?

The static encoding format functions as a fixed digital mirror of a bank identification key previously registered by the user with the financial institution.

Once the image is generated, it remains valid indefinitely and can be printed on plastic posters or shared repeatedly via messaging apps.

This model allows the issuer to set a fixed amount for the charge or leave the financial field completely open for the payer to fill in.

Due to its extremely simple setup, it perfectly suits freelancers, small service providers, and quick transfers between friends.

The flexibility of Pix via QR Code Static technology reduces checkout time at small establishments that sell products at a fixed price.

However, because it does not generate a unique identifier per transaction, the cash register control system requires manual verification of each receipt on the mobile phone screen.

How does dynamic code operate and how does it optimize business cash flow control?

The dynamic coding model is based on a data architecture connected in real time to the banking institution's application programming interface (API).

Each sale initiated in the system generates a unique, one-time-use code that contains detailed information about the commercial transaction.

This feature allows you to automatically include the buyer's name, a breakdown of the products purchased, the application of promotional discounts, and the automatic calculation of interest.

As soon as the payment is processed by the bank, the commercial automation system receives an instant notification and updates the operational workflow.

Using automation based on financial APIs protects the company against sophisticated fraud involving the spoofing of banking app screens and altered digital receipts.
