When users insert the power card into the meter, errors in card reading and writing may occur due to the card being unplugged too early (usually requiring a waiting time of more than half a minute), the card not being fully inserted by the user, or the user immediately unplugging and reinserting the card because they believe it is not properly inserted, resulting in the inability to input electricity into the meter. When placing the power card in the system to read it, the system prompts "The power card has not been fully written, please repair the card...". Generally speaking, after this message appears, simply use the "User Card Repair" operation in the "Electric Card Operation" to repair the card.

However, there is also a special situation. For new user cards issued for the first time, sometimes even after successful card repair, the electricity meter does not recognize it (especially with 3D software). To deal with this situation, it is generally advisable to first clear the card (the 3B software needs to use the "clear card" operation to clear the card without removing the card after successful repair, while the 3D software directly uses the "old card reset" operation to clear the card), and then use the "resend new user card" operation to issue the card. One thing to note after using a new card to "resend a new user card" is that after daily settlement, the electricity sales amount in the daily settlement report should be deducted from the electricity sales amount in the resend new user card report to obtain the actual electricity sales amount. If it is handled by our factory service personnel, the issuance record in the Issucard library can be deleted after clearing the card. Then, as a new user, you can issue cards and sell electricity (without the need for account registration).
