I have a China oil Kunlun fuel card from a friend, which is valid for 3 years. It's an anonymous, non-loss-reporting, non-replacement card. How can I check the balance?

First, the way to check the balance is to directly hold the card to the PetroChina networked gas station to check the amount.

Second, the national fuel card is a fuel card launched by Lianyuan Tianxia for national car owners. You can ask for invoices after refueling at gas stations (non-alliance gas stations) such as PetroChina and Sinopec, and reimburse invoices at Lianyuan Tianxia Platform. The reimbursement amount is directly returned to the user's fuel account, which can be consumed and withdrawn; You can also scan the code at the gas station of Youlian Tianxia Alliance and refuel directly. Gift card is a refueling gift card launched by Youlian Tianxia, which can be used for business appreciation, employee welfare, holiday gifts and so on. After the gift card is successfully purchased, the system will automatically send a card secret message to the mobile phone number of the purchasing member, and the purchaser can copy the card secret for redemption, or forward it or give it to other members for redemption. After the gift card is successfully redeemed, a national refueling card will be automatically generated, which can be used for refueling at Alliance gas stations or reimbursement of invoices and cash withdrawals.

3. PetroChina Kunlun Fuel Card

1. Named card: a prepaid consumer card issued by a customer to record the cardholder's relevant information. Including personal business cards and team cards. The fleet card is similar to the main and auxiliary cards of Sinopec. The fuel card is the same as the chip surface, but the name in the upper right corner of the card surface is different.

(1) Personal business card: a prepaid consumption card issued for individual customers, which can be used for points, loss reporting, card replacement and account cancellation.

(2) Fleet card: a prepaid consumption card issued for fleet customers, which consists of a management card and several driver cards, and can be used to report the loss, reissue the card and cancel the account. The management card can not only manage the driver card, but also have the function of recharging consumption; The driver card can refuel, and other functions are set by the management card. Petrochina's fleet cards sell well in the market.

(3) Bearer card: commonly known as "red ribbon card", the chip has a red ribbon logo on the upper right corner, which has good market liquidity and can be oil-free. The prepaid consumer card issued by the customer without recording the main information of the card can be recharged repeatedly. Because the "red ribbon card" is anonymous, it is also a good hard currency for gifts. The red ribbon card of PetroChina has played many games in the non-oil business of Kunlun convenience store. In recent years, the focus of PetroChina's work has always mentioned that the oil card is not moist, and the "non" inside is non-oil, which is unexpected and impossible.

(4) Special cards: Special cards are special oils, such as fishing boat fuel card, airplane fuel card, PetroChina Guo Lin fuel card, PetroChina ironworker fuel card, taxi fuel card (PetroChina Shouqi fuel card), teacher card, etc. The price of special oil for agriculture, forestry, fishery and animal husbandry here is the lowest, which can be much cheaper than the retail price. Taxi fuel card should be similar to the price of big customers.
