Growing calls are being made to create a better customer verification code for the purchase of railway ticket online in China, as many are concerned about the current system leading up to the Spring Festival buying rush.

The current verification system employs a method of matching pictures with a corresponding description.

The verification process prompted numerous complaints, including the size and style of the pictures, as well as the available options people have to choose from when trying to verify a picture they can barely see.

Buying a railway ticket online has gained more and more popularity in recent years, as it's faster and more convenient.

As such, growing calls are being made for a more user-friendly verification system for the benefit of both ticket buyers and the national transportation system as a whole.
