Systems and methods using a network of wearable devices to support secure payment for a user are described. The network of wearable devices may include a wearable secure unit including a first short-range transceiver, a wearable sensory unit including a second short-range transceiver, and a wearable communication unit including a third short-range transceiver and a long-range transceiver. The systems and methods may include receiving a transaction request from a merchant device. Thereafter, the systems and methods may obtain information from the wearable secure unit configured to provide an environment in which processes and data are securely stored and executed. The systems and methods may also obtain information from the wearable sensory unit configured to capture and compare biometrics of the user with a stored profile. Based on the obtained information, the systems and methods may instruct the wearable communication unit to transmit to the merchant device user authentication data.
