JP Morgan Chase has notified employees assigned to its state-of-the-art corporate base in New York that they must submit their biometric data to enter the high-value structure.
The investment bank had previously envisioned for the registration of physical identifiers at its new high-rise to be voluntary.
Nevertheless, staff of the US's largest bank who have commenced employment at the main office since last month have received emails stating that biometric entry was now "compulsory".
Biometric access necessitates staff to scan their hand geometry to pass through entry points in the main floor instead of using their access passes.
The main office building, which apparently required an investment of $3bn to construct, will ultimately act as a home for ten thousand workers once it is entirely staffed later this year.
The financial company did not provide a statement but it is understood that the use of biological markers for entry is intended to make the facility better protected.
There are special provisions for some employees who will still be able to use a traditional pass for entry, although the requirements for who will employ more standard badge entry remains unclear.
In addition to the introduction of palm and eye scanners, the organization has also released the "Corporate Access" mobile app, which serves as a electronic pass and hub for worker amenities.
The platform permits users to handle guest registration, explore building layouts of the building and arrange in advance meals from the premises' multiple on-site dining vendors.
The deployment of enhanced security measures comes as US corporations, especially those with significant operations in New York, look to strengthen protection following the attack of the top executive of one of the US's largest health insurers in July.
Brian Thompson, the boss of the insurance giant, was fatally shot not far from the bank's location.
It is uncertain if JP Morgan aims to implement the biometric system for staff at its branches in other important economic centers, such as the British financial district.
The decision comes within controversy over the use of digital tools to observe staff by their employers, including monitoring physical presence metrics.
Previously, all staff members on mixed remote-office plans were instructed they must return to the workplace five days a week.
The organization's head, the prominent banker, has characterized the company's new skyscraper as a "tangible expression" of the company.
Dimon, one of the world's most powerful bankers, this week warned that the likelihood of the financial markets facing a downturn was far greater than many financiers thought.
