The banking leader has informed employees working at its recently built headquarters in New York that they are required to submit their physical characteristics to enter the high-value structure.
The investment bank had originally intended for the collection of physical identifiers at its recently opened skyscraper to be optional.
However, employees of the biggest American bank who have started operations at the corporate hub since August have been sent emails stating that biometric entry was now "required".
This security method requires staff to scan their hand geometry to gain access access portals in the lobby instead of using their access passes.
The main office building, which allegedly cost $3bn to construct, will in time serve as a home for ten thousand employees once it is entirely staffed in the coming months.
The financial company opted not to respond but it is assumed that the implementation of biometric data for admission is intended to make the premises more secure.
There are exceptions for certain staff members who will still be able to use a badge for access, although the standards for who will employ more standard badge entry remains undefined.
In addition to the introduction of physical identifier systems, the company has also launched the "Corporate Access" digital platform, which serves as a electronic pass and hub for employee services.
The application permits users to manage guest registration, explore interior guides of the facility and schedule dining from the premises' multiple food service providers.
The deployment of tighter entry controls comes as business organizations, notably those with significant operations in New York, look to strengthen protection following the attack of the chief executive of one of the US's largest health insurers in recent months.
Brian Thompson, the leader of the healthcare company, was fatally shot not far from JP Morgan's offices.
It is unclear if the financial firm plans to introduce physical identifier entry for personnel at its branches in other key banking hubs, such as the UK capital.
The action comes amid debate over the implementation of technology to observe staff by their companies, including monitoring office attendance levels.
Earlier this year, all the bank's employees on flexible arrangements were directed they have to report to the physical location on a daily basis.
The bank's chief executive, Jamie Dimon, has described the bank's recently opened 60-storey headquarters as a "impressive representation" of the institution.
The banker, one of the influential banking figures, lately cautioned that the likelihood of the financial markets experiencing a decline was far greater than many investors believed.
