After the transaction is complete, the user can view the purchase history to the admin by submitting the e-KTP
as user identity.
Electronic Identity Card (e-KTP) is a modern card made based on RFID (radio frequency identification).
This card, both in terms of physical and usage, has a computerized function. Each e-KTP has a different unique
code that will be read using an RFID reader and processed by a microcontroller. Furthermore, the data will be
compared with data registered in the database. (Fajri, & Oktaviana, 2019). The e-KTP program in Indonesia
began in 2009 with the designation of four cities as national pilot projects. The four cities are Padang, Makassar,
Yogyakarta and Denpasar.
The use of fingerprint identification as data validation during financial transactions or when payments are
made. AS608 Optical Fingerprint is a finger scanner. How AS608 works: finger is placed on the surface of the
glass prism and light occurs through the face of the other prism. The angle of incidence is greater than the
critical angle and therefore all light is actually reflected internally from the troughs of the finger. However, the
ridge absorbed most of the light. In this way the valley appears bright and the ridge dark. This results in a high
contrast fingerprint image.

3. Results and discussion

3.1. Hardware Testing

Tests carried out on a payment system using e-KTP based on Radio Frequency Identification apply Visual
Basic.Net and Arduino testing, where tests were carried out on the application. The trick is to test whether the
functions contained in the tool have functioned as desired. From the results of the tests carried out, all the sub
blocks and the system work well. In Table 1, a list of Payment System Testing using e-KTP is shown.

Table 1. List of Payment System Testing Using e-KTP

Test item Data tested
Login admin Enter your ID and password
Registration Registering user data
Payment Change data and add balances
Purchase history Reducing the balance according to the price of the goods

3.2. Testing on the Software Interface

Testing the software interface is done using a computer by opening Visual Basic.Net which functions as an
interface from the system to the user. Furthermore, to be able to display payment results, customers or buyers
must visit the cashier who manages the application. After successfully registering and filling the balance, the
customers / buyers can make a payment. Figure 2 shows the payment interface.
The purpose of the Admin testing is to ensure that the admin function is running correctly when the admin
updates data and adds user balances. Admin testing can be seen in Figure 3 as updating data and filling balances.

4. Conclusion

The resulting hardware system successfully reads and receives data input from the e-KTP and fingerprint
validation. The system built successfully registers user data. The system was successfully built to increase and
decrease the balance according to the simulation of the price of goods. The resulting system can store data,
balances and transaction history of the user. The resulting system can show data and balances via admin, then
