Smile to Pay for Everyday Transactions


Hello Reader,

We’ll explore cutting-edge innovation in payments — facial recognition payment and its nitty-gritty

Let’s dive in and stay informed!


Imagine walking into a grocery store without any cash, credit cards, or even your phone and still being able to make a payment. That’s the power of facial recognition payment (FRP). This cutting-edge technology, which is already available in China, enables users to complete transactions simply by scanning their faces. The global market for contactless biometrics technology is expected to reach $18.6 billion by 2026 at a 19.1% CAGR.

FRP: What Is It, and How Does It Work?

FRP is a biometric payment technology that verifies a user's identity during transactions by using facial recognition software. The technology takes a picture of the user's face and compares it to images stored in a database using machine learning algorithms. If the images match, the user is granted access to their payment information, and the transaction can be processed.

FRP offers a more secure and convenient alternative to traditional payment methods, such as passwords or pin numbers, by eliminating the need for physical payment devices or remembering login credentials.

FRP requires point-of-sale machines equipped with a connected device with a small camera to access the facial information database. Customers must first associate their facial image with the payment system, and once setup is complete, making purchases becomes a simple process. The customer selects the FRP option on the checkout machine, positions themselves in front of the camera for scanning, confirms the payment on the screen, and the transaction is completed.

Face recognition and deep learning algorithms assist in recognizing the customer's face, extracting features from the face, validating them against the registered facial image, and determining the customer's liveliness.


So far so good, what about the implications?

FRP technology offers several advantages, such as convenience, speed, and enhanced security, enabling users to make payments simply by gazing into a camera, eliminating the need for physical cards or passwords.

However, there are drawbacks, including technical issues with facial recognition, privacy concerns, the cost of implementation, and a lack of awareness. Additionally, the use of facial recognition technology raises ethical questions about the handling of personal information and its potential misuse. The technology may also present inaccuracies for individuals from ethnic or racial minorities and can result in money being taken from the wrong person's account in cases of misidentification.

To overcome the drawbacks of FRP, solution providers use additional authentication like PIN validation and fingerprint checking. This two level authentication helps identify the right person and avoid fraudulent attempts.

There is also no guarantee against third-party providers' databases containing millions of public biometric data being hacked. The appropriate regulatory bodies should implement the FRP solution by taking the necessary steps and disseminating the guidelines.

Trade-Off between the Advantages and Pitfalls

Regulatory bodies have a challenging role in balancing the benefits and drawbacks of facial recognition technology and ensuring its responsible use, protecting users privacy and rights.

  1. Privacy: Storing personal biometric data raises concerns about the protection of personal information and potential misuse
  2. Accuracy: The technology can be affected by various factors, leading to incorrect identifications. Regulators must ensure the technology is reliable and accurate.
  3. Bias and Discrimination: If the technology is trained on biased data, it could result in discrimination against certain groups, such as ethnic communities
  4. Security: Facial recognition systems are vulnerable to hacking and cyberattacks, putting users' sensitive information at risk. Regulators must ensure proper security measures are in place
  5. Ethics: The use of facial recognition technology raises ethical questions about personal privacy and the potential for misuse. Regulators must create policies and guidelines that ensure the technology is used in an ethical and responsible manner

Global Trends

China is a leader in biometric payment technology, but it's rapidly being adopted in other regions. In mid-2017, Alipay introduced its Smile to Pay facial recognition payment system in a KFC store in Hangzhou, marking the first commercial application of the technology globally. Alipay and WeChat Pay also introduced face-scanning machines, with usage of these machines growing at a rate of 16% to 20%. Mastercard followed suit by launching its own Smile to Pay solution in Brazil in May 2022, targeting the Middle East and Asia.

Despite the concerns raised by consumers, the adoption of facial recognition payment solutions remains a topic of interest in the coming years. Let's wait and see how retail customers will embrace this high-tech payment method.
