ABSTRACT:
A card is provided for cleaning transducer heads of magnetically-encoded card reading machines. The card includes a surface region disposed for contacting such a transducer head and releasably holds a head cleaning solvent adjacent the surface region. The material forming the surface region may be visually distinguishable when it is holding solvent as compared to when it is not. Further, this material may be translucent when holding solvent. If so, the material immediately next to the solvent-holding material is a color which is visible through the material. Also, the card may have layers which are joined by heat-bonding. The side of the card opposite from the surface region then preferably is another color.
