THEKEY is a decentralized biological system of equipment that confirms massive data and tokens that use blocking. The THEKEY project team is currently developing a block-based dynamic multidimensional ID (BDMI) and ID Verification (IDV) device using Personal Identification Data only approved by government agencies. Focusing on validating symbols will be a key part of THEKEY's core framework. NEO’s multi-programming language resemblance and NEOVM’s lightweight, high-speed and expandable work with THEKEY have been widely agreed upon and promoted in various fields. THEKEY IDV uses a unique multidimensional definition (BDMI) integrated. intended for the identification of a person authorized by a public body (PII). The Android and iOS gadgets are a big deal with little to no confirmation, such as a strong building staircase. Calculations vary in addition to the cost of the screen.
