Abstract: A cleaning strip for cash and credit card machines comprises a strip coated with flock fibers and made of a substrate, wherein two opposing strip edges define a machine direction and the width of the strip measured transversely to an insertion direction into a cash and credit card machine corresponds substantially to the length of a side edge of a banknote or credit card suitable for use in a cash and credit card machine to be cleaned. On at least one of the surfaces thereof, the strip has at least three transverse strips (14), mounted transversely to the machine direction at a distance from each other and provided with a coating made of flock fibers.
Abstract: The inventive cleaning card for magnetic track and chip card read/write devices has a card-shaped support (2) which consists of a nonwoven material and which is partially layered with a soft cleaning material (6). Said cleaning material (6) is located on several predetermined surface areas of the support (2) and consists of a fibrous flock with densely stuck-on individual fibres of predetermined length and with a predetermined diameter, which project essentially perperdincularly away from the support (2).
Abstract: The card-shaped plastic carrier 2 of a cleaning card for magnetic track and chip card writing/reading devices is partially layered with a codable material as well as with soft cleaning material. The cleaning material consists of a fiber flock with individual fibers extending essentially perpendicularly from the carrier and tightly packed and adhesively attached to the carrier and having predetermined lengths and predetermined diameters. The codable material is in the form of a pigmented screen printed color printed in several screen printing processes; then on at least side of the card pre-given surface areas for the cleaning material is layered by screen printing processes with a two-component adhesive 8; then the individual fibers are set into the adhesive beds of the individual surface areas essentially perpendicularly; the flat plastic carrier 2 with the layers is subjected to a drying process; and then the nonbonded fibers are washed away.
