JP Morgan Chase has notified staff members assigned to its new headquarters in New York that they are required to share their physical characteristics to gain entry the multi-billion structure.
The investment bank had previously intended for the collection of employee biometrics at its recently opened high-rise to be discretionary.
However, employees of the biggest American bank who have started operations at the new headquarters since August have been sent electronic messages stating that physical scan entry was now "required".
Biometric access necessitates employees to provide their hand geometry to gain access entry points in the main floor instead of using their ID badges.
The main office building, which reportedly required an investment of $3 billion to construct, will ultimately act as a base for 10,000 employees once it is fully occupied in the coming months.
The financial company opted not to respond but it is believed that the implementation of physical identifiers for access is intended to make the building better protected.
There are exceptions for some employees who will retain the ability to use a traditional pass for entry, although the criteria for who will utilize more standard badge entry remains undefined.
Alongside the introduction of physical identifier systems, the company has also released the "Corporate Access" mobile app, which functions as a digital badge and hub for staff resources.
The platform permits users to manage external entry, navigate interior guides of the building and schedule dining from the premises' multiple food service providers.
The introduction of stricter access protocols comes as business organizations, notably those with significant operations in New York, look to increase security following the incident of the CEO of one of the US's largest health insurers in recent months.
The executive, the leader of the insurance giant, was the victim of the attack not far from the bank's location.
It is uncertain if the banking institution intends to deploy the biometric system for staff at its offices in other important economic centers, such as the UK capital.
The move comes within debate over the use of technology to track workers by their companies, including observing workplace presence.
Earlier this year, all the bank's employees on flexible arrangements were directed they are required to come back to the workplace five days a week.
The company's leader, the financial executive, has referred to the company's recently opened tower as a "tangible expression" of the company.
Dimon, one of the world's most powerful bankers, this week warned that the probability of the American markets experiencing a decline was far greater than many financiers anticipated.
