The banking leader has told personnel working at its state-of-the-art main office in Manhattan that they must submit their biometric data to access the multibillion-dollar skyscraper.
The banking corporation had previously envisioned for the registration of employee biometrics at its new skyscraper to be voluntary.
Yet, employees of the biggest American bank who have begun work at the main office since last month have been sent emails stating that biometric access was now "compulsory".
The new entry system requires staff to submit their eye patterns to pass through access portals in the lobby rather than scanning their access passes.
The main office building, which allegedly was built for three billion dollars to develop, will in time function as a workplace for thousands of staff members once it is entirely staffed in the coming months.
The financial company did not provide a statement but it is understood that the implementation of biometric data for access is intended to make the facility more secure.
There are exemptions for specific personnel who will still be able to use a ID card for entry, although the standards for who will utilize more conventional entry methods remains unclear.
Alongside the implementation of physical identifier systems, the bank has also released the "JPMC Work" mobile app, which serves as a digital badge and hub for staff resources.
The application enables employees to handle guest registration, use indoor maps of the building and arrange in advance dining from the facility's multiple on-site dining vendors.
The implementation of tighter entry controls comes as US corporations, particularly those with substantial activities in New York, look to strengthen protection following the incident of the CEO of one of the biggest American insurance companies in summer.
The executive, the head of the insurance giant, was fatally shot not far from JP Morgan's offices.
It is uncertain if JP Morgan plans to implement the biometric system for employees at its offices in other major financial centres, such as the British financial district.
The decision comes amid debate over the implementation of technology to observe staff by their employers, including tracking workplace presence.
In recent months, all the bank's employees on mixed remote-office plans were directed they have to report to the workplace on a daily basis.
The bank's chief executive, the financial executive, has characterized JP Morgan's new 60-storey headquarters as a "beautiful physical manifestation" of the institution.
The banker, one of the global financial leaders, this week warned that the likelihood of the US stock market experiencing a decline was far greater than many investors anticipated.
