Reading the hotel logo from the existing card failed.
What you want to ask is the reason why reading the hotel logo from the existing card failed? The reason for this is the following:
1. Card damage: If the card is bent, scratched or the magnetic stripe is damaged, the card reader cannot read the information on the card.
2. Card reader failure: If the card reader itself fails, such as read head damage or circuit failure, the information on the card cannot be read.
3. Magnetic field interference: There is strong magnetic field interference around the card reader, such as TV, computer, mobile phone and other electronic equipment, which will affect the normal work of the card reader.
