Data Stamping Service API

Stamp and validate digital objects with geolocation, date, time, a 2D barcode, and information on when it was issued and if or when it expires.

Acoer has released their Data Stamping Service API so that users can stamp and validate digital objects with geolocation, date, time, and a 2D barcode. The stamp will also contain information on when it was issued and if or when it expires. There is even an option to create stamps that aren't valid until a future date and time.
