Su Tong Card ETC can be recharged online via WeChat, or at designated service outlets or ATMs. The WeChat recharge method is as follows: 1. Prepare a mobile with NFC functionality or a recharge device with top-up capability; 2. Place the Su Tong Card on the back of the phone, and WeChat will automatically recognize it and pop up a recharge window. Then select the existing device and start recharging; 3. Choose the Su Tong Card. If it's a pass card from another province, you can also select to recharge; 4. Next, choose the desired recharge amount and payment method. After successful payment, the recharge is complete. The method for recharging at service outlets is: Bring all relevant documents to the outlet and follow the staff's instructions. The ATM recharge method is: Go to the bank's self-service ATM terminal and manually complete the top-up.









I think mobile top-up is the most convenient. You can download the 'Jiangsu ETC' or 'Sutongbao' app from the mobile app store, register and log in, then bind your Sutong card and bank card to top up. Just click the top-up button on the homepage, select your payment method, and the money will be credited immediately. You can also check your travel records and balance on your ! Nowadays, many bank apps also support top-ups. For example, I often use Alipay—just find the ETC top-up service in the Citizen Center, and it will take effect within 3 minutes after topping up. Remember, if you plan to hit the highway after topping up, it's best to do it near your OBU device so it can sync automatically.

I prefer offline top-ups. There are self-service top-up machines at nearby highway service areas where you can insert your card, enter the amount, and pay by scanning a QR code. The service points next to toll booths are also open on weekends—just bring your card to the counter and specify the amount to top up with cash or by card. Some gas stations and Sinopec Easy Joy convenience stores in the city also have top-up points. Just be careful not to let your card expire. Last time, I met a driver who hadn’t topped up in two years and had to go to the customer service center to reactivate the card, which was a hassle. Bank counters also offer top-up services—just bring your card and ID.

Using online banking is quite simple. Log in to the Jiangsu Expressway official website or the online banking of the bank where your card is bound, find the ETC recharge menu, enter the card number and amount, then transfer the money. However, it's important to note that the transfer account name must match the ETC user name, and the ETC card number must be clearly written in the payment remarks. My colleague forgot to write the card number last time, and the money was suspended in the system for a week before it was resolved. The Su Tong Card WeChat -program also has a recharge channel, and the card binding operation is similar to the APP. If your card is in arrears when used in other provinces, you can recharge it at any nationwide networked service point. For example, Shandong Expressway stations can handle Su Tong Card recharges.

Automatic bank card top-up is the most hassle-free option. Just sign an automatic deduction agreement at the ETC service point, link your bank card and set the top-up amount. When the balance falls below 50 yuan, it will automatically recharge 500 yuan. Since I linked mine, I've never worried about the balance, and passing through toll stations is faster. For company vehicle , you can also set a monthly spending limit and get a unified invoice at the end of the month for accounting purposes, which is much more convenient for accountants. However, remember to regularly check the balance of your linked card. My neighbor Old Zhang didn't notice his card had insufficient funds, causing the automatic top-up to fail and getting blacklisted, which was a real hassle to resolve.

It's convenient for corporate fleets to recharge using a corporate account. Bring the business license and company seal to the Su Tong Card customer service center to open a corporate account, pre-deposit funds into the account, and then the vehicle cards below can share the balance. Each time the finance department transfers funds for recharge, the invoice is more hassle-free compared to personal cards. Online corporate payments can also be transferred to the designated account, and the funds will be automatically credited by noting the corporate account number. Sometimes you may encounter a stored-value card reading failure at the highway exit. Don't panic in such situations; you can resolve it by swiping the card at a manual lane. Remember to check if the device's signal is blocked by a film when you get back.
