A biometric input device is used to obtain biometric data from a user. The biometric data is used to determine host card emulation (HCE) parameters that are associated with the user and are used to access a payment account. An interface device that is associated with the biometric input device receives the HCE parameters. The interface device includes a secure execution environment (SEE). A processor in the SEE decrypts and stores the HCE parameters in the memory of the SEE and executes an HCE instance. The HCE instance uses a communication interface to interact with a payment terminal using a contactless communication protocol. The interaction provides payment data to the payment terminal, which is then sent along a payment channel for processing. The HCE instance is then erased, and the SEE is then available for use by another user for another transaction using a different payment account.
