• Which mobile devices can read ADNA?

    In-house testing indicates that most mainstream Android or iOS devices produced in the last few years will easily read ADNA. In part, this high tolerance for device variance is attributable to the efficient image processing approach we are using. Our ongoing testing program has included devices from Apple, Blackberry, HTC, Huawei, Samsung, Xiaomi, and ZTE.
  • Is internet access required when scanning ADNA?
    Yes, in most instances internet access is required. While our pattern technology supports local data encoding, the rich and easily modifiable experiences for which ADNA is most appropriate require an internet connection.
  • How important is lighting?
    ADNA is very tolerant to variations in lighting levels, particularly if the reading device is equipped with a light source to compensate for very low-light conditions. Harsh lighting can be a challenge if the surface containing ADNA is too reflective.
  • How close do you need to be to read ADNA?
    This varies with pattern magnification and the zoom level set in the app but we do most of our test reading with the device about 10 cm (~4 inches) from the host surface.
  • What data can be gathered for each scan event?
    This will differ between operating systems due to platform policies but generally, with user permission, the app will gather sufficient location, context, and device data to help us all understand users better in order to more efficiently deliver increasing levels of value to them in the future.
  • What is the smallest area that can be coded?
    In most of the use-cases that we are envisioning for this generation of ADNA, the smallest block of pattern will be about 9mm x 9mm.
  • Do you offer reading performance testing as part of prototyping?
    Yes. We believe that empirical evidence is the only basis on which to make good decisions regarding the right balance between readability and unobtrusiveness.
  • Is reading performance better with high resolution cameras?
    Not necessarily, because our proprietary image processing approach makes highly efficient use of relatively small amounts of visual data in order to deliver great performance on a wide variety of devices.
  • Is it possible to use multiple ADNA patterns on a single product or package?
    Yes, but this obviously needs to be done with careful consideration of the user experience.
  • How does ADNA compare with QR codes?
    The below matrix shows our view of the important differences between these two pattern systems. We fundamentally feel that QR codes serve a useful but very different and limited purpose from ADNA.
