The application provides a data transmission device and equipment, the data transmission device comprises an interface module, a network module, a first circuit, a second circuit and a wireless communication module, wherein the network module receives Ethernet data through the interface module, and converts the Ethernet data into TTL signals and then transmits the TTL signals to the first circuit and the second circuit respectively; the first circuit converts the TTL signals output by the network module into RS232 data and then transmits the RS232 data to the wireless communication module, the wireless communication module converts the RS232 data into wireless signals and then transmits the wireless signals to a wireless terminal; and the second circuit converts the received TTL signals into RS485 data and then transmits the RS485 data to a wired terminal. Through the data transmission device, the host call data of a queuing calling system can be sent to a wireless calling device and a wired calling device, one host can cover a larger environment area, and the host is no longer limited in engineering deployment and use, so that flexibility is improved and application scenarios are enriched.

Disclosed embodiments include identity verification and management services in which users authenticate their identities during an enrollment process, and may access and modify their identity information via a secure portal. The enrollment process includes collecting various identifying data and biometric data of a user. A live interview portion during the enrollment process is used to check the liveness and verify the collected identifying data and biometric data. Once the user is enrolled, the user's identity can be verified for multiple entities using the same enrolled identity, and the user can manage the specific data used to verify their identity with different entities. This provides users with the ability to use their authenticated / verified identity across various industries, markets, locations, and the like, while keeping their identifying data private. Other embodiments may be described and / or claimed.
