The invention provides a device for determining a signature from an article in a reading volume of the device. The device comprises a source operable to generate a coherent beam and a beam directing member operable to direct the coherent beam into the reading volume. The device also comprises a detector arrangement which is used for collecting signals created by scatter of the coherent beam within the reading volume, wherein different ones of the signals relate to scatter from different parts of the reading volume, and possesses a numerical aperture greater than a predetermined minimum, and aprocessor operable to determine a signature for an article in the reading volume from the collected signals. Use of such device can be repeated whenever required to test authenticity of the article. By using this system, it has been discovered that it is essentially pointless to make effort and spend expense to make specially prepared tokens, since unique characteristics are measurable in a straightforward manner from a wide variety of every day articles.
