Kit and method for improving the security of a card reader
A kit and method for improving the security of a card reader having a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, where each wafer is shaped and sized so that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader. The plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers.
1. A kit for improving the security of a card reader, the kit comprising:
a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, wherein each wafer is shaped or sized such that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader,
wherein the plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers,
wherein one or more wafers in the plurality of wafers is shaped or sized to fit the cavity in the card reader such that movement of the stack of wafers within the cavity is restricted,
wherein the one or more wafers are shaped or sized such that the one or more wafers comprise one or more protrusions or edges for contacting one or more parts of an internal structure of the card reader such that movement of the stack of wafers within the cavity is restricted, and
wherein the one or more wafers comprising the one or more protrusions or edges comprises a first wafer that is for insertion into the card reader prior to insertion of any other wafer in the plurality of wafers.
2. A kit for improving the security of a card reader, the kit comprising:
a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, wherein each wafer is shaped or sized such that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader,
wherein the plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers,
wherein one or more wafers in the plurality of wafers is shaped or sized to fit the cavity in the card reader such that movement of the stack of wafers within the cavity is restricted,
wherein the one or more wafers are shaped or sized such that the one or more wafers comprise one or more protrusions or edges for contacting one or more parts of an internal structure of the card reader such that movement of the stack of wafers within the cavity is restricted, and
wherein the one or more protrusions are deformable to enable the respective wafer to be inserted into the card reader via the card slot.
3. A kit for improving the security of a card reader, the kit comprising:
a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, wherein each wafer is shaped or sized such that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader,
wherein the plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers,
wherein the plurality of wafers comprises a final wafer that is for insertion into the card reader after all other wafers in the plurality of wafers have been inserted into the card reader, and
wherein the final wafer is shaped to prevent an unauthorised object positioned in the cavity from contacting a magnetic stripe or an electronic chip of a card as or when the card is inserted into the card reader.
4. A kit for improving the security of a card reader, the kit comprising:
a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, wherein each wafer is shaped or sized such that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader,
wherein the plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers,
wherein the plurality of wafers comprises a final wafer that is for insertion into the card reader after all other wafers in the plurality of wafers have been inserted into the card reader, and
wherein the final wafer is shaped such that the stack of wafers prevents a card from being fully inserted into the card reader when an unauthorised object is also present in the card reader above the final wafer.
5. A method for improving the security of a card reader, comprising the steps of:
providing a kit for improving the security of a card reader, the kit comprising:
a plurality of wafers for insertion individually into the card reader via a card slot in the card reader, wherein each wafer is shaped or sized such that the wafer can be inserted through the card slot in an insertion direction and positioned in a cavity in the card reader,
wherein the plurality of wafers are configured to couple together when inside the cavity to form a stack of wafers, and
individually inserting each wafer in the plurality of wafers into the card reader via the card slot in the card reader,
wherein the plurality of wafers are configured to couple together using an adhesive applied to a surface of at least one wafer in the plurality of wafers, and wherein, for each of the at least one wafers with an adhesive applied to its surface, the method further comprises applying a temporary barrier coating to the adhesive prior to inserting the wafer into the card reader.
6. The method as claimed in claim 5 , wherein the temporary barrier coating comprises a volatile substance.
