Abstract

A temporary carrier of a removable memory card ( 2 ) is in the shape of a flat card ( 1 ), where the removable memory card ( 2 ) forms an element to be released from the flat card body ( 1 ). The removable memory card ( 2 ) has at least five additional contacts ( 4 ) for temporary usage before the removable memory card is removed from the flat card ( 1 ) body. The additional contacts ( 4 ) take up a smaller surface as a contact field ( 5 ) of a standardized flat card ( 1 ). The removable memory card ( 2 ) is located within the flat card ( 1 ) in such a way that the position of additional contacts ( 4 ) corresponds to the position of a standardized flat card ( 1 ) contact field ( 5 ). The suitable sixth additional switch contact ( 8 ) can be used to switch secure elements. The temporary carrier is inserted into a standard burning device, which operates with it in the same way as it would with a common card with a contact field ( 5 ).

First claim

The invention claimed is:

1. A temporary carrier comprising:
a flat card body; and
a removable memory card that has inner circuits and a microSD contact interface with a different contact layout than a contact field of a flat payment card, said removable memory card adapted to store uploaded payment application data and/or software, wherein:
said flat card body includes said removable memory card as a limited element intended for release from the flat card body by breaking off the removable memory card from the flat card body along a release line;
the removable memory card is equipped with at least five additional contacts on its surface outside the microSD contact interface, these additional contacts enabling a temporary use before the removable memory card is released from the flat card body, wherein the at least five additional contacts correspond by their positions to contacts C1, C2, C3, C5, and C7 according to ISO 7816, and wherein additional contacts corresponding to the contacts C1 and C5 are interconnected with the inner circuits of the removable memory card to supply the inner circuits with power, where C1 represents power supply, C5 represents grounding, and the additional contact corresponding to the contact C2 provides a reset of the inner circuit, the additional contact corresponding to the contact C3 provides for clocking of communication that runs over the additional contacts, and the additional contact corresponding to the contact C7 provides data input and output;
a sum of surfaces of additional contacts on the removable memory card is smaller than the contact field of the flat payment card whereby every individual additional contact takes up a smaller surface than a corresponding contact in the contact field of the flat payment card;
gaps between the additional contacts substantially correspond to the gaps between contacts in the contact field of the flat payment card;
the removable memory card is oriented and placed within the flat card body in such a way that a position of additional contacts within outer parameters of the temporary carrier corresponds to the position of the contact field of the flat payment card where the contact field of the flat payment card overlays predetermined contact positions for the flat card body, and;
additional contacts are interconnected with the inner circuits of the removable memory card independently from the microSD contact interface where the additional contacts and the microSD contact interface are placed on the removable memory card;
the removable memory card has at least two secure elements and a sixth additional contact that is interconnected with the inner circuits for exclusive switching of one secure element into an active mode, and wherein the sixth additional contact is located in the axis of three additional contacts and, by its position, corresponds to a C4 contact according to ISO 7816;
wherein the removable memory card has a disconnector connected between the additional contacts and the inner circuits of the removable memory card in order to disconnect the additional contacts from the inner circuits before the removable memory card is released from the flat card body, and the disconnector is in the form of conductors comprising gate array that go out of the removable memory card to other parts of the flat card body through a break-off line and then the conductors return through the break-off line back to the removable memory card, and the disconnector conductors run through the break-off lines that connect the temporary carrier with the removable memory card; and
the temporary carrier further comprises a security foil at least on one side, wherein the security foil has protection elements signaling its removal from the temporary carrier and covers the microSD contact interface and/or additional contacts.

2. A temporary carrier of a removable memory card according to claim 1 , wherein from the at least five additional contacts there is one additional contact provided for power supply, one additional contact provided for data transmission to the inner circuits, one additional contact provided for grounding, one additional contact provided for reset of the inner circuit, and one additional contact provided for clocking of communication that runs through the additional contacts.

3. A temporary carrier of a removable memory card according to claim 1 , wherein the removable memory card has a NFC communication element with an antenna while at least parts of the additional contacts are located outside an antenna projection to an outer part of the removable memory card.

4. A temporary carrier of a removable memory card according to claim 1 , wherein the disconnector is in the form of a programmable gate array.

5. A temporary carrier of a removable memory card according to claim 1 , further comprising a foil that holds the removable memory card in the flat card body.

6. A temporary carrier comprising:
a flat card body; and
a removable memory card that has inner circuits and a contact interface with a different contact layout than a contact field of a flat payment card, said removable memory card adapted to store uploaded payment application data and/or software, wherein:
said flat card body includes said removable memory card as a limited element intended for release from the flat card body by breaking off the removable memory card from the flat card body along a release line,
the removable memory card is equipped with at least five additional contacts on its surface outside the contact interface, these additional contacts enabling a temporary use before the removable memory card is released from the flat card body,
a sum of surfaces of additional contacts on the removable memory card is smaller than the contact field of the flat payment card,
gaps between the additional contacts substantially correspond to the gaps between contacts in the contact field of the flat payment card,
the removable memory card is oriented and placed within the flat card body in such a way that a position of additional contacts within outer parameters of the temporary carrier corresponds to the position of the contact field of the flat payment card where the contact field of the flat payment card overlays predetermined contact positions for the flat card body, and
additional contacts are interconnected with the inner circuits of the removable memory card independently from the contact interface where the additional contacts and the contact interface are placed on the removable memory card, wherein on an outer surface of the temporary carrier in the location of the removable memory card there is a foil with at least five contacts on an outer side of the foil, wherein contacts correspond by their location and shape to corresponding contacts of the contact field of the flat payment card, wherein the foil overlaps the break-off line, and wherein contacts on the foil are on the inner side of the foil interconnected with the additional contacts on the removable memory card and the foil can be removed from the removable memory card body.

7. A temporary carrier of a removable memory card according to claim 6 , wherein the contacts on the outer side of the foil are interconnected with touch pads on the inner side of the foil, and the touch pads are closely pressed to the additional contacts on the removable memory card.

8. A temporary carrier of a removable memory card according to claim 7 , wherein the touch pads overlap from the inner side of the foil.

9. A temporary carrier of a removable memory card according to claim 1 , wherein the flat card body is adapted such that the removable memory card is released by means of contact needles designed for the contact field of the flat payment card.
