    Countermark with a specified reading geography. To read a Geo-Locked Countermark, you must enable the “Location” setting on the phone. The phone must also be in the specified area that the Issuer has set for each Countermark.

What’s the difference between Public and Private?

    All Countermark Users can read a Public Countermark. A typical use for Public Countermarks is marketing operations or free data for use in the public domain.

    Only a specified Group of Users can read a Private Countermark. These Users are typically specialists that must have access to protected data.

How do I add a User to a Group and edit Group membership details?

    An individual with a phone who is permitted to read a Countermark. A ‘Public’ User can read a Countermark at all locations without access limits. A ‘Private’ User can only read a Countermark on authorized phones.

  • Group:

    A number of Users the Issuer collects into a Group that share access to a common Countermark.
