What is the reason for being unable to pay for Subject 1 on 12123?

When paying the exam fee, the prompt "Payment failed: The response data from the payment platform is empty" appears, preventing the payment of the exam fee. At this time, you should check if your mobile network is functioning properly, try switching between data connection and WiFi, or restart your phone. It could also be due to an outdated software version that needs to be updated. If none of the above methods work, it is recommended to go to the local vehicle management office to make the payment. Relevant information about the driver's license is as follows: 1. Introduction: The People's Republic of China Motor Vehicle Driver's License, abbreviated as driver's license, also known as "driving license," is a necessary document for motor vehicle drivers issued in accordance with the laws of the People's Republic of China. 2. Exam content: The exam subjects include traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving).

When encountering a payment failure for Subject 1, I usually first check if the platform system is under maintenance or upgrade. Recently, the Traffic Management 12123 server often updates at night, causing the payment channel to become unavailable. It could also be due to poor mobile network signal leading to payment interruption, especially in basements or remote areas. I've tried several times where the payment got stuck halfway, and I had to switch to home WiFi to restart the process. Additionally, it's important to confirm if the bank card balance is sufficient. Last year, my cousin forgot that there was only 50 yuan left in his card when paying the 100 yuan driving test fee, resulting in a failed transaction. By the way, frequent errors might trigger the bank's risk control system. In such cases, switching to another card or contacting customer service is the quickest solution.

Payment failures are mostly due to operational errors. Last time when I helped my mom, I noticed she entered the wrong expiration date for her bank card—missing one digit caused the system to reject it. It's also common to accidentally tap the cancel button or have the payment page expire from staying too long. My coach reminded me that it's best to link the bank card to the 12123 platform in advance, so you can just use fingerprint payment at checkout. If paying via a browser, remember to clear the cache and refresh the page—once I got stuck at the verification code step, but it worked immediately after refreshing. The most overlooked issue is when the payment app crashes due to full phone storage; deleting some photos can easily fix it.

The most likely reason for being unable to pay for Subject 1 is bank-side restrictions. I have a credit card that usually works for payments, but driving test fees exceeding 500 are subject to single transaction limits. Some bank cards also have separate online payment permissions that need to be specifically activated. If you see a 'Bank Rejected Transaction' message, it's definitely a card issue - the quickest solution is to switch to a debit card or use Alipay balance. If failures persist, consider the possibility of a frozen bank account. Last month, my friend didn't notice a scam text message, and his bank temporarily blocked the card for three days, preventing any payments. The most reliable way is to directly check your account status at an ATM.
