Sieveo

Sieveo is a German systems integrator working on RAIN RFID for vehicle identification, part of the Utsch group. Its speciality is DigSig, the digital signature approach that lets a tag be verified offline: the data is held and cryptographically signed on the tag itself rather than checked against a central database, which matters for number plates and official documents. The company supplies dual frequency tags readable by both smartphone and UHF reader, plus the issuance stations that personalise and sign them.
