QR code mobile payment process
The QR code is easily recognized by the cell’s or tablet’s camera using a special program – a QR code scanner. You do not need to photograph the code in order to do this, you just need to point the camera so that the entire square of the QR encryption fits the scanner window. After data handling, the decoded information will appear on the screen of the smartphone or tablet.
As QR code for mobile payment is greatly implemented in the business sphere, it’s important to get acquainted with the payment vehicle, which is the following:
● The buyer sweeps over the QR code with the specialized app on the gadget, automatically receives the seller’s QR code mobile payment details (rather than filling out all the details manually), selects the payment card, detects the sum (not always, often price data is already displayed automatically), affirms the QR mobile payment, and currency is debited from his/her card.
● Funds are credited to the seller’s payment card.
● The seller receives a confirmation about QR code-based mobile payment in a POS cash register system or gets a message on his/her smartphone (via QR code platform or simply on the cell) about the credited defrayal.
The mobile payments using QR codes are also advantageous because the E-Recipe soft provides for the refusal to print paper bills of sale. An electronic check is generated in the system, registered in the required system, and supplemented with a QR code, after which it transfers to the device in digital form.
QR code app development: the importance of professional team
The implemented by the Wallet Factory Company QR code payment method in the required app works correctly even under heavy load. The group of professionals is able to create high-quality code, optimize it, and provide everything necessary for QR code payment security. The encryption is always displayed in a square shape. The most important element of the code is a matrix. Its intricate drawing consists of black squares and lines, which are called modules. The number of modules can vary, depending on how much information needs to be hidden in the image. In the smallest QR codes, there may be nearly 441 modules. The largest and capacious variants can contain 31329 modules.
The solution can present available statistics for each created QR code: how many times the encryption was read and how many defrayals were made. Each code may be disabled at the right time, as well as changed (for example, in order to adjust the amount). There is no need to replace the code itself when commutating the code parameters. The QR code app development is performed all the time, so the mentioned company constantly improves the product and adapts it according to the modern requirements. Technically, it’s possible to put a lot of data in a QR code, but this will make it difficult to sweep over the code via mobile gadgets. However, the encryption can store not only text, but also images, links, sound recordings, and other types of data. The developed QR payment platform is one of the Wallet Factory specialist’s fields, so the product is on the highest level.
