Configuration with the payment button in the mobile communication device, the way the payment process is started
On the interface side ( 7 ), a removable memory card ( 2 ), on which at least one payment card unit is located ( 5 ), appears to be a removable memory card ( 2 ) for the extension of the mobile communication device's ( 4 ) memory capacity up till the moment when the payment purpose button ( 1 ) is physically pressed. Then the removable memory card ( 2 ) switches into the payment function's access mode and is made accessible on its interface ( 7 ) as a card with a Secure Element ( 3 ) having at least one payment card unit ( 5 ). After the termination and/or interruption of the payment process, the removable memory card ( 2 ) switches into the access mode for the memory capacity extension function of the mobile communication device ( 4 ). This configuration and method increase the security of the payment process while retaining high level of manipulation comfort. At the mobile communication device with a payment purpose button ( 1 ) it is possible to switch the access mode exclusively by physical press of the hardware payment button ( 1 ) by which the unauthorized start of the payment application without the user's knowledge is prevented.
1. A removable memory card for use in a mobile communication device having a hardware payment button, the removable memory card comprising:
a secure element;
a contactless communication element;
a payment card unit; and
a memory,
wherein the removable memory card has a first access mode for extension of a memory capacity of the mobile communication device in which access to the secure element and to the contactless communication element is blocked, and
a second access mode for a payment function of the removable memory card with authorized access to the secure element and to the contactless communication element with the payment card unit, wherein the second access mode is active only after a physical press of the hardware payment button.
2. The removable memory card of claim 1 , further comprising a payment terminal unit that is accessible exclusively in the second access mode.
3. The removable memory card of claim 1 , further comprising an antenna connected to the contactless communication element.
4. The removable memory card of claim 1 , wherein the removable memory card is an SD or microSD card.
5. The removable memory card of claim 1 , wherein the communication element is a near-field communication (NFC) element.
6. A system for contactless payment, the system comprising:
a mobile communication device having a hardware payment button; and
a removable memory card comprising a secure element, a contactless communication element, a payment card unit, and a memory,
wherein the removable memory card has a first access mode for extending a memory capacity of the mobile communication device, wherein access to the secure element and to the contactless communication element is blocked, and
a second access mode for a payment function of the removable memory card with authorized access to the secure element and to the contactless communication element with the payment card unit, wherein the second access mode is active only after a physical press of the hardware payment button.
7. The system of claim 6 , wherein the removable memory card further comprises a payment terminal unit that is accessible exclusively in the second access mode.
8. The system of claim 6 , wherein the removable memory card further comprises an antenna connected to the contactless communication element.
9. The system of claim 6 , wherein the mobile communication device is configured to block emulation of a signal from the payment button on an impulse from another input to the mobile communication device.
10. The system of claim 6 , wherein the removable memory card is an SD or microSD card.
11. The system of claim 6 , wherein the communication element is a near-field communication (NFC) element.
12. A method for starting a payment process from a mobile communication device having a hardware payment button, the method comprising:
communicating between the mobile communication device and an interface of a removable memory card inserted into the mobile communication device, the removable memory card having a payment card unit, a secure element, a contactless communication element, and a memory,
wherein, before the payment process is started, the removable memory card is in a first access mode for extending a memory capacity of the mobile communication device in which the payment card unit, the secure element, and the contactless communication element are inaccessible from the interface, and
wherein, after a physical press of the hardware payment button, the removable memory card switches into a second access mode for a payment function of the removable memory card with allowed access to the payment card unit, the secure element, and the contactless communication element via the interface.
13. The method of claim 12 , wherein the removable memory card comprises a secure element with a payment terminal unit that is accessible only after the removable memory card is switched into the second access mode.
14. The method of claim 12 , wherein, after the payment process is ended or interrupted, the removable memory card switches back into the first access mode.
15. The method of claim 12 , wherein the removable memory card further comprises an antenna connected to the contactless communication element.
16. The method of claim 12 , further comprising blocking an emulation of a signal from the payment button on an impulse from another input to the mobile communication device.
17. The method of claim 12 , wherein the removable memory card is an SD or microSD card.
18. The method of claim 12 , wherein the communication element is a near-field communication (NFC) element.
