The Budapest transport system has recently (2023) implemented an innovative approach to ticket validation, utilizing both Near Field Communication (NFC) and QR codes. This dual-method system aims to enhance efficiency and user experience.
NFC Technology Implementation
Process and Benefits:
- Convenient Validation: NFC-stickers are placed on vehicle doors of BKK lines and at station entrances on metro lines. Users validate their tickets or passes by holding their phones 1-3 cm away from the sticker. This proximity triggers an animated image on the device, confirming successful validation.
- No App Required: One-step validation with NFC does not require logging into the BudapestGO app. Users simply unlock their phones, significantly streamlining the process.
- Speed: The NFC validation process is approximately 10 seconds faster than QR code scanning, as it eliminates the need to open any apps. This quick and seamless interaction is particularly beneficial during peak hours, reducing congestion at entry points.
Placement of NFC-Stickers:
- Metro Entrances: Stickers are located on ticket validation machines below the QR code and the paper ticket slot.
- Trams, Buses, Trolleybuses, and Suburban Trains: Stickers are placed on the side of the vehicles next to the doors, adjacent to the QR code stickers.
QR Code Technology
Process and Benefits:
- App Integration: Users can still validate their tickets purchased through other digital ticket apps using QR code scanning. This method requires opening the specific app and scanning the code.
- Compatibility: QR codes provide a reliable alternative for users without NFC-enabled phones, ensuring the validation system remains accessible to all passengers.
Placement of QR Codes:
- Metro Entrances and Vehicles: QR code stickers are placed alongside NFC stickers on validation machines and vehicle doors, ensuring that both methods are readily available.
Observations and Findings
During my visit to Budapest, I had the opportunity to use this system and realized how convenient it was compared to QR code scanning. It saves multiple seconds because you do not need to open your camera; you can simply hold your phone near the NFC tag. This experience sparked my interest in further exploring this technology.
I discovered that NFC stickers or cards can be easily purchased and configured, which I plan to experiment with in the near future. Some practical uses of NFC stickers include sharing WiFi passwords, facilitating fundraising through flyers, and sharing photos.
