2. How Contactless Payments with Barcodes Work |
Barcode-based contactless payments operate by encoding transaction data in a scannable barcode, which can be read by a smartphone or other scanning device. This eliminates the need for physical touch, thereby reducing the risk of contamination, and offering both consumers and businesses a faster, more secure payment option. |
In a typical restaurant setting, a customer can use a mobile app to scan a barcode on a receipt or menu to initiate payment. This barcode might contain a unique transaction ID, the amount to be paid, and other relevant details. The process involves the following steps: |
1.Transaction Generation: When a customer orders food at a restaurant, the total bill is generated and displayed as a scannable barcode. This barcode can either be printed on a paper receipt or displayed on a digital screen (e.g., on a mobile device or tablet). |
2.Scanning: The customer uses a smartphone or another device with a barcode scanning function to capture the barcode. The scanning process can be done using a dedicated mobile payment app such as PayPay, Line Pay, or a similar service. In some cases, specialized payment terminals at the restaurant are used to scan the barcode directly from the customer's device. |
3.Data Transmission: Once the barcode is scanned, the data encoded in the barcode is transmitted to a server, which processes the payment. This server communicates with the customer's bank or digital wallet to authorize the transaction. |
4.Payment Confirmation: After the payment is successfully processed, the system sends a confirmation to both the customer and the restaurant. This may be in the form of a digital receipt or a notification on the customer's mobile device. |
|
3. Technologies Behind Barcode-Based Contactless Payments |
Barcode-based contactless payment systems rely on two primary technologies: QR codes and one-dimensional barcodes (1D barcodes). While QR codes are the most commonly used format for contactless payments, 1D barcodes still play a significant role in certain contexts. |
QR Codes: A QR (Quick Response) code is a two-dimensional barcode that stores data in both horizontal and vertical axes. This allows QR codes to hold a larger amount of information than traditional 1D barcodes. QR codes are particularly effective in mobile payment applications because they are easily scanned by smartphone cameras. |
1D Barcodes: Traditional 1D barcodes, such as the Code 128 or EAN-13 format, are commonly used for product identification and inventory management. However, in the context of contactless payments, their application is less versatile than QR codes. These barcodes can still be used for simpler applications, such as linking a payment to a specific transaction ID or amount. |
NFC (Near Field Communication): Although NFC-based systems (such as FeliCa and Apple Pay) are also prevalent in Japan, barcode-based systems are gaining ground due to their simplicity and flexibility. NFC involves radio-frequency identification (RFID) technology, where the user taps their phone or card on a payment terminal. However, barcodes do not require additional hardware like NFC-enabled terminals, making them more cost-effective and scalable. |
