The financial institution has told employees assigned to its new main office in Manhattan that they have to submit their biometric data to access the multibillion-dollar building.
The banking corporation had previously intended for the collection of employee biometrics at its new skyscraper to be optional.
Nevertheless, employees of the leading financial institution who have begun work at the main office since this summer have obtained communications stating that biometric access was now "required".
The new entry system demands personnel to scan their eye patterns to enter security gates in the lobby in place of using their identification cards.
The main office building, which apparently required an investment of $3 billion to build, will in time function as a base for ten thousand staff members once it is entirely staffed in the coming months.
JP Morgan did not provide a statement but it is believed that the use of physical identifiers for access is created to make the premises better protected.
There are exceptions for some employees who will continue to have the option to use a ID card for entry, although the standards for who will use more standard badge entry remains unclear.
Complementing the introduction of biometric readers, the organization has also launched the "Work at JPMC" smartphone application, which serves as a digital badge and portal for staff resources.
The app permits users to coordinate guest registration, explore interior guides of the building and arrange in advance dining from the facility's 19 restaurant options.
The deployment of stricter access protocols comes as US corporations, particularly those with major presence in New York, look to increase security following the attack of the top executive of one of the US's largest health insurers in July.
The executive, the boss of the insurance giant, was the victim of the attack not far from JP Morgan's offices.
It is not known if the financial firm aims to deploy biometric access for personnel at its branches in other major financial centres, such as the UK capital.
The move comes within discussion over the use of technology to track workers by their employers, including observing physical presence metrics.
In recent months, all the bank's employees on flexible arrangements were directed they must return to the workplace full-time.
The bank's chief executive, the prominent banker, has described JP Morgan's state-of-the-art skyscraper as a "tangible expression" of the institution.
The executive, one of the influential banking figures, recently cautioned that the probability of the US stock market facing a downturn was far greater than many financiers anticipated.
