Abstract
Systems and methods for facilitating transactions between a mobile device and a service machine are disclosed. The system comprises a wireless radio frequency (RF) communication module configured to transmit a RF signal using a RF technology with a given operation range; and a hardware attenuation module configured to attenuate the RF signal to a predefined Transmitted Power Output (TPO) in a first attenuation mode such that communication between the apparatus and the mobile device starts only when the mobile device is positioned relative to the service machine in a detection range that is significantly smaller than the given operation range.

Apparatus for facilitating transactions between a mobile device and a service machine, comprising:
- a) a wireless radio frequency (RF) communication module configured to transmit a RF signal using a RF technology with a given operation range;
- and
- b) a hardware attenuation module configured to attenuate the RF signal of the RF communication module to a predefined first Transmitted Power Output (TPO) such that communication between the apparatus and the mobile device starts only when the mobile device is positioned relative to the service machine in a detection range limited by the first TPO, wherein the detection range is in the range of 0-25 cm,
- wherein upon completion of a handshake between the RF communication module and the mobile device at the first TPO, the hardware attenuation module increases the RF signal of the RF communication module to a second TPO with a communication range larger than the detection range while in a connected state with the mobile device.
A method for facilitating transactions between a mobile device and a service machine, comprising:
- a) transmitting a radio frequency (RF) signal by an RF communication module using a RF technology with a given operation range;
- b) by a hardware attenuation module, attenuating the RF signal of the RF communication module to a predefined first Transmitted Power Output (TPO) that communication between the apparatus and the mobile device starts only when the mobile device is positioned relative to the service machine in a detection range limited by the first TPO, wherein the detection range is in the range of 0-25 cm;
- and
- c) by the hardware attenuation module, while in a connected state with the mobile device, increasing the RF signal to a second TPO with a communication range larger than the detection range upon completion of a handshake at the first TPO between the RF communication module and the mobile device.
