Abstract
This paper describes a design that applies the e-money system through the use of e-identity cards (hereinafter referred to as
e-KTP). The aim is not only to make transactions easier and to make transaction time efficient, it also reduces the use of
cash as a form of security in carrying large amounts of money and being inconvenienced with refunds in small
denominations. The method used in this research is design and implementation. This system is made by utilizing e-KTP
based on Radio Frequency Identification and equipped with additional security in the form of Fingerprint Biometrics. From
the results of testing several e-KTP samples, all of them were successfully recorded in the database and successfully read
again. Data that has been successfully recorded into the database is in the form of user identity, nominal money deposited
and the balance after the transaction. This system is expected to be integrated into the integrated and multifunctional e-KTP
system so that we are no longer bothered with having to carry a variety of other cards.

1. Introduction

Transactions are activities carried out by a person that can result in the exchange of goods or money, both
increasing and decreasing. However, the large number of exchanges using paper and metal money makes
transactions inefficient because we have to carry a lot of money, this makes money pile up in the wallet and
uncomfortable when using it. A lot of resources are wasted because money is damaged or obsolete due to age
or improper use. To reduce the use of money and save manufacturing resources, the developer is currently
implementing Radio Frequency Identification technology which aims to make transactions easier by simply
utilizing the e-KTP (electronic identity card) provided by the government.
An automation system that controls the supply of goods for supermarkets in Nigeria using RFID which
operates at a frequency of 13.56 MHz (Boyinbode & Akinyede, 2015). Likewise, an RFID-based smart trolley
system has been developed which can provide a display on the trolley in the form of the amount of money to
be paid based on the number of items placed in the cart. The goal is to save queuing time so that when you
arrive at the cashier, you just have to pay immediately without the need to scan goods via bar codes. (Devi,
Kaarthik, Selvi, Nandhini, &Priya, 2017). In a paper written by Gunasagar et al, they describe a smart billing
system that utilizes RFID and weight sensors. In this system, the function of RFID is to check each product
placed in the trolley and display the bill amount on the LCD (Gunasagar, &Balachander, 2020). A smart trolley
system that is used for shopping in malls and shopping centers was developed (Machhirke, Priyanka, Rathod,
Petkar, &Golait, 2017).
In these papers, a system that uses e-KTP is proposed for a home security system, namely by using the RFID
technology embedded in the e-KTP to be able to open and close house doors (Andriansyah et al., 2017),
Mustolih, Lenggana, & Mulyana (2019), Putra, Marwanto, & Qomaruddin (2017). A system that the use of the
e-KTP system should apply a decentralized network model, especially for storing e-KTP data without violating
privacy laws (Awangga, Harani, &Setyawan, 2019). In the research conducted by Fajri, et al, they proposed an
