The financial institution has informed personnel working at its recently built headquarters in Manhattan that they must submit their biological identifiers to gain entry the multibillion-dollar structure.
The banking corporation had originally intended for the collection of employee biometrics at its new skyscraper to be discretionary.
However, employees of the biggest American bank who have begun work at the corporate hub since this summer have obtained communications stating that biometric entry was now "compulsory".
This security method necessitates staff to submit their fingerprints to pass through entry points in the lobby instead of scanning their access passes.
The main office building, which reportedly required an investment of $3 billion to build, will in time serve as a home for ten thousand staff members once it is entirely staffed later this year.
JP Morgan declined to comment but it is understood that the employment of biometric data for admission is designed to make the building better protected.
There are special provisions for some employees who will continue to have the option to use a ID card for admission, although the standards for who will use more standard badge entry remains unclear.
In addition to the introduction of biometric readers, the company has also released the "Corporate Access" mobile app, which functions as a digital badge and center for employee services.
The application enables staff to handle external entry, explore interior guides of the facility and pre-order food from the building's 19 food service providers.
The deployment of stricter access protocols comes as business organizations, notably those with significant operations in the city, look to strengthen protection following the incident of the top executive of one of the US's largest health insurers in summer.
The executive, the leader of the insurance giant, was the victim of the attack not far from the bank's location.
It is unclear if the banking institution aims to introduce physical identifier entry for staff at its branches in other important economic centers, such as London.
The decision comes within discussion over the employment of systems to observe staff by their companies, including observing office attendance levels.
In recent months, all staff members on hybrid work schedules were instructed they have to report to the workplace on a daily basis.
The bank's chief executive, the prominent banker, has described JP Morgan's recently opened 60-storey headquarters as a "beautiful physical manifestation" of the company.
Dimon, one of the influential banking figures, lately warned that the likelihood of the American markets crashing was significantly higher than many financiers anticipated.
