Unique Identification Authority of India (UIDAI), the government agency in charge of Aadhaar, is expected to make it mandatory for manufacturers to embed the Aadhaar encryption key into biometric devices using Aadhaar authentication, according to a report by the Business Standard.Although all current Aadhaar-connected mobile devices are STQC certified, embedding UIDAI‘s encryption key into the devices will provide an additional layer of security to the hardware as biometric-based digital payments become more prevalent throughout the country. Amitabh Kant, National Institution for Transforming India, recently said India could introduce biometric payments within three years, thereby eliminating the need for cash and typical electronic payment methods.
