# Introduction Welcome to SenseCrypt eID, your gateway to leveraging SenseCrypt technology for generating Privacy Preserving, Non-Biometric data-structures/QR codes with Biometric Verifiability. SenseCrypt's SensePrint eID QR codes, when integrated into an eID document like a PDF, or when printed on a physically verifiable ID card, facilitate offline/online verification of the ID holder's facial features and eID attributes. In their raw form, SensePrints are just bytes which can also be stored in databases, embedded in NFC technology, etc. It is these raw bytes that are embedded within SensePrint eID QR codes. > SenseCrypt technology ensures privacy preservation as neither the facial image, nor the biometric feature vectors are embedded within the QR code/raw data structures generated. > > Unlike other possible solutions, our technology is not a compression / obfuscation technology. There is truly no way to correlate two different eID QR codes/raw data structures even when they are generated from the same data. > > Also, there are **no** Biometric templates within the QR code / raw data structures in either compressed or encrypted form. This makes this solution reduce privacy compliance risks with legislation/acts around the world while, at the same time, offering complete peace of mind regarding data breach risks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
