The irony is that for most websites, if the recognition algorithm is used comprehensively, the recognition rate of machines has exceeded that of humans.

2. Voice verification code
-------------
High cost .. Best results
The machine recognition rate is poor .. Less than 10%

3. SMS Verification Code
---------
The cost is higher than the image method and lower than the voice verification.
Machine recognition rate: 100%

Although the text message verification code recognition rate is 100%, and the recognition technology is more difficult than the image verification code method, the only obstacle is the cost ..
However, due to the use of SMS and other devices, the recognition cost is high. Currently, it takes about 5 cents to identify a mobile phone verification code .. In the next few years, with the growth of Scale benefits, it is expected to reduce the cost of text message recognition to a single cent
