The document describes an e-wallet application that allows users to make payments using Near Field Communication (NFC) technology on Android smartphones. It discusses how the application works, including user registration and login, adding payment balances by activating vouchers, and making expenditures by scanning NFC tags on smart posters. The application transfers user and transaction data between the smartphone app and a web server for validation. The document also evaluates the application's performance and network usage, finding that data reception uses more bandwidth than transmission and that internet connectivity was the main constraint reported by users. It concludes by recommending a focus on security and expanding platform support for broader use.

E wallet nfc service payment
- 1. E-WALLET APPLICATION SERVICE PAYMENT USING NFC (NEAR FIELD COMMUNICATION) TECHNOLOGY ON SMARTPHONE BASED ANDROID OPERATING SYSTEM I Gede Tirta Nata 114080096 1st Advisor 2nd Advisor AGUS VIRGONO, Ir., MT SURYA MICHRANDI NASUTION, ST., MT (NIK : 93660083-1) (NIK : 10860738-3)
- 2. Background : • e-Wallet a service payment application to transact virtual money with shopping vouchers via android smartphone (your money in smartphone as a wallet). • Instant, flexible and simple for user (access and protect all important your information). • Using NFC technology on RFID contactless system with reader/writer mode based standard ISO/IEC 14443 and FeliCa scheme. • Needed a system that can transfer some user data to or from web server, activate voucher code and shopping payment.
- 3. Purpose : • Activate account on registration-login from the application with input Username, IMEI and PIN to get listed in web server. • Add payment balance user on voucher card with activate 16 digits voucher. • Expenditure transactions on smartphone apps to get closer to logo smartposter (NFC tag) then scan it and send product data to the web server.
- 4. Problem Limitation : • e-Wallet app specifically for smartphone android platform 2.3 (Gingerbread) and above who support NFC tech. • This project is only for transfer of data transaction from smartposter to e-Wallet app and validation in web server. • This system not discuss the network security etc. • Only use NFC tech reader/writer operating mode with standardization ISO/IEC 14443 and FeliCa schemes. • Payment model made alternative with shopping voucher as income user (buyers).
- 5. Problem Limitation : Cont… • Assumptions shopping transactions conducted in a shopping center where the user brings smartphone include e-Wallet app. • Assumptions administrator set up the transaction in the website and of course shopping center provide free WiFi Hotspot. • Assumptions shopping vouchers are only available at stores (retail) where user can buy it if their balance is less and each of the products is mounted smartposter that embedded information product.
- 6. THEORY
- 7. Electronic Wallet : e-Wallet systems are common several types : Business to Business (B2B), Business to Consumer (B2C) and Consumer to Consumer (C2C). Suited to provide a safe way for smartphone users to store and use online shopping information. Consists of software and information that provides security and encryption personal info transaction. Information like ID, PIN number, billing and date transaction can be managed easily from server administrator.
- 9. NFC : NFC is a set of wireless connectivity based RFID tech which uses magnetic field induction to enable communication between electronic device within a close (<2 inch). NFC evolved contactless system refers standard ISO/IEC 14443, operates at 13.56 MHz with data transmission speed 106 – 424 kbps NFC defined 2 types mode operation as an initiator and a target communication, namely Active Mode and Passive Mode. NFC support 3 types method operation very unique compatible smart card standard, such Reader/Writer Method, Peer-to-Peer (P2P) Method and Emulation Card Method.
- 10. NFC :
- 11. NFC Tag NFC tag is a small area of programming information that can be embedded in poster, on billboards or ads in the product retail stores. Dimensions for NFC tag format is determined to be 85.46 x 53.92 x 0.76 mm (± tolerance). The process of making tags using RTD (Record Type Definition NDEF Signature), to verify the integrity and authenticity of content. The benefits will be more secure for the long term but weakness if you want to change the new information then all tags must also be replaced and it takes time and is expensive.
- 12. Smartposter : Smartposter is billboards or posters displayed in public area are equipped with contactless NFC tag, typically RFID embedded in them. Smartposter simplify customer interaction with the product being advertised, smartposter also significantly increase marketing potential.
- 13. SYSTEM MODEL
- 14. System Design : • Registration-Login • Activate Voucher • Shopping Payment
- 15. SD : Registration / Login START DATABASE REGISTRATION DATA USER POST DATA USER SUCCESS ? YES NO LOGIN DATA USER FINISH
- 16. SD : Activate Voucher START DATABASE USER BUY VOUCHER INPUT CODE VOUCHER SUCCESS ? YES NO FINISH GET DATA VOUCHER GET METHOD REQUEST FROM USER INCOME OUTPUT USER UPDATE STATUS
- 17. SD : Shopping Payment START DATABASE SUCCESS ? FINISH LOGIN DATA USER ACTIVATE NFC FEATURE ON SMARTPHONE CEK SALDO ENOUGH LESS GET DATA VOUCHER INCOME OUTPUT USER NEAR SMARTPHONE TO SMARTPOSTER GET ID PRODUCT TAP TRANSACTION VERIFICATION PAYMENT YES NO
- 21. Testing #login
- 24. Analysis #Network Statistics Network Statstics in DDMS with connection EDGE, 3G and WiFi based TX (left) and RX (right). The maximum values is 10.29 kbps which indicates that RX is always greater than TX.
- 25. Analysis #Network Statistics Network Statstics in DDMS with connection EDGE, 3G and WiFi based TX and RX. Graphs of total data packets sent and received on connection EDGE, 3G and WiFi
- 27. Conclusion : • Network Statistics in DDMS with connection speeds an EDGE, 3G and WiFi based on the TX (transmitter) and RX (receiver), the maximum value is 10.29 kbps which indicates that RX is always greater than TX. • Resource usage required size of 2.36 MB so that need 2.39 MB free storage can be installed. Heap size 9.383 MB, 8.485 MB storage allocation so percentage of memory to used is 90.43%. • Constraints perceived by the respondents while running this application is Internet Connection (47%). • App dev. suitable location according responding chose in Shopping Centers (40%). • Use IMEI smartphone to help authenticate user accounts with system single user, single wallet, single account prevent misuse by other.
- 28. Suggestion : • Expected application design must focused on security system on the web server such as uses http security (https) portal and added functionality for transportation service, cinema and home security. • Expected next project development this application not only works on Android OS but also applied on Apple iOS, Windows Phone and Blackberry smartphone so that all users can benefit of this technology.
