A system, comprising: a biological tissue sample cassette as used in pathology having a tissue sample chamber, an inner tissue sample chamber within the tissue sample chamber, and a tissue cassette lid, wherein a bottom of the inner tissue sample chamber and a part of the tissue cassette lid that is used to close the inner tissue sample chamber comprises holes that are smaller than holes in the rest of the bottom of the tissue sample chamber and the cassette lid; an inlay configured to be used with said biological tissue sample cassette for the purpose of turning said biological tissue sample cassette into a device traceable with RFID technology; wherein the inlay is tagged with an RFID chip, said inlay having an inlay part with an antenna and an inlay part with the RFID chip, wherein the RFID tagged inlay is bonded to a layer consisting of a polymer or one or more other compounds that resist(s) deteriorating influences of chemicals that make contact with the inlay when the inlay is positioned in the tissue sample chamber of the biological tissue sample cassette during processing of a tissue sample that is also present in the tissue sample chamber; wherein the inlay and the layer to which it is bonded have the form of a rectangular frame around an opening; wherein the inlay is formed in a way to allow fluid paraffin to flow through the holes in the bottom of the tissue sample chamber when a biological tissue sample together with the tissue sample cassette is embedded in paraffin; wherein the inlay is further formed in a way to allow said chemicals to flow through the holes in the bottom of the tissue sample chamber and the cassette lid when said tissue sample chamber is closed with said cassette lid during said processing of a tissue sample in said tissue sample chamber; characterized in that the inlay and the layer are formed in a way that the opening enables the inlay and said layer to fit in the tissue sample chamber of the biological tissue sample cassette between a wall of the tissue sample chamber and a wall of the inner tissue sample chamber and around the inner tissue sample chamber. a biological tissue sample cassette as used in pathology having a tissue sample chamber, an inner tissue sample chamber within the tissue sample chamber, and a tissue cassette lid, wherein a bottom of the inner tissue sample chamber and a part of the tissue cassette lid that is used to close the inner tissue sample chamber comprises holes that are smaller than holes in the rest of the bottom of the tissue sample chamber and the cassette lid; an inlay configured to be used with said biological tissue sample cassette for the purpose of turning said biological tissue sample cassette into a device traceable with RFID technology; wherein the inlay is tagged with an RFID chip, said inlay having an inlay part with an antenna and an inlay part with the RFID chip, wherein the RFID tagged inlay is bonded to a layer consisting of a polymer or one or more other compounds that resist(s) deteriorating influences of chemicals that make contact with the inlay when the inlay is positioned in the tissue sample chamber of the biological tissue sample cassette during processing of a tissue sample that is also present in the tissue sample chamber; wherein the inlay and the layer to which it is bonded have the form of a rectangular frame around an opening; wherein the inlay is formed in a way to allow fluid paraffin to flow through the holes in the bottom of the tissue sample chamber when a biological tissue sample together with the tissue sample cassette is embedded in paraffin; wherein the inlay is further formed in a way to allow said chemicals to flow through the holes in the bottom of the tissue sample chamber and the cassette lid when said tissue sample chamber is closed with said cassette lid during said processing of a tissue sample in said tissue sample chamber; characterized in that the inlay and the layer are formed in a way that the opening enables the inlay and said layer to fit in the tissue sample chamber of the biological tissue sample cassette between a wall of the tissue sample chamber and a wall of the inner tissue sample chamber and around the inner tissue sample chamber.
