Abstract

The development of wireless technology will reach the fifth generation (5G). If this condition occurs, then there will be many objects that can interconnect and exchange data. Embedded system is one area that will play many roles. One of them is the use of Near Field Communication (NFC). NFC is a short-range communication tool that has been used in many applications. NFC is one of the payment methods that will continue to be used by consumers. The development of this use must be accompanied by increasing trust. In practice, NFC has three modes: peer to peer, read / write and card emulation mode. In the state of card emulation mode, NFC mounted on a smartphone starts to bring up the Host Card Emulation which is launched on Android Kitkat 4.4. This condition allows the possibilies of interruptions or attacks. Then it needs to be examined the system that runs whether there is a gap or not. This study analyzed this with the response time parameters and the distance of the device. Card emulation conditions on NFC-enabled mobile with HCE show that communication can be done in combination with distance and the results show that distance does not affect response time. As long as it is still in the reader range, NFC-enabled mobile can still be read.
