Acerta is a Mexico-based company with more than 20 years of experience integrating solutions to process mass information. They were bidding for a government project that would develop a biometric enrollment system for the National Tax Recovery Agency of Mexico (SAT). SAT needed a flexible enrollment system to biometrically enroll 10,000 citizens per day. The requirements included capturing fingerprints, face, iris, signature and documents using online and offline stations nationwide, a biometric background check against 15 million personal records and more than 10 external services needed to be checked in order to issue an official Electronic Signature certificate for each citizen. There are 12 process variants with the possibility to work for other companies or government agencies.
