Tips: Dear customers 1. The glue card in this link is IC authorized card, which cannot be used for copying. Please confirm before purchase. If you have any questions, please consult customer service. 2. After receiving the card, you need to authorize it and enter it into the system. Make sure that the card you previously used is encrypted and not a duplicate card. Ask the software provider. Not being able to duplicate means the chip number of the card is fixed; it cannot be erased or changed. It is not a UID card, and the 0 sector cannot be modified. However, the card can be re-authorized for use. 3. All our cards are unencrypted. Is your system encrypted? Some system providers encrypt your system so that you can only purchase cards from them, so that only the corresponding password card can be used, which makes buyers only able to purchase cards from the system provider. 4. If you need to buy IC card, as long as the IC card is not encrypted, you can authorize it after buying it, and the IC card in this store is not encrypted; if you need to buy ID card, the system supports ID card, you can use it after authorization. 5. However, there are some operational problems. Our card seller is not very familiar with it. You can first consult your system provider before purchasing.
