The banking leader has told employees moving into its state-of-the-art main office in Manhattan that they have to provide their biometric data to access the multi-billion building.
The financial firm had previously intended for the collection of biometric data at its new tower to be optional.
Nevertheless, employees of the leading financial institution who have begun work at the corporate hub since August have received communications stating that physical scan entry was now "compulsory".
The new entry system requires employees to scan their fingerprints to gain access security gates in the entrance area in place of using their ID badges.
The main office building, which apparently cost $3 billion to construct, will in time serve as a workplace for thousands of staff members once it is fully occupied in the coming months.
JP Morgan did not provide a statement but it is understood that the employment of biometric data for access is designed to make the facility safer.
There are exemptions for specific personnel who will continue to have the option to use a traditional pass for access, although the requirements for who will use more standard badge entry remains unspecified.
Complementing the deployment of physical identifier systems, the organization has also released the "Work at JPMC" smartphone application, which acts as a electronic pass and center for worker amenities.
The application enables staff to coordinate visitor access, explore interior guides of the premises and pre-order food from the premises' 19 restaurant options.
The implementation of stricter access protocols comes as US corporations, particularly those with significant operations in the city, look to increase security following the incident of the chief executive of one of the US's largest health insurers in summer.
The executive, the head of the healthcare company, was the victim of the attack not far from the bank's location.
It is not known if the banking institution intends to introduce the biometric system for personnel at its offices in other major financial centres, such as the UK capital.
The move comes during controversy over the employment of systems to monitor employees by their organizations, including monitoring office attendance levels.
Earlier this year, all the bank's employees on mixed remote-office plans were directed they are required to come back to the office on a daily basis.
The bank's chief executive, Jamie Dimon, has described the company's recently opened tower as a "impressive representation" of the company.
Dimon, one of the influential banking figures, recently cautioned that the probability of the American markets experiencing a decline was significantly higher than many investors thought.
