I'm from an advertising company. I made a batch of room cards for a hotel, but the software always showed card writing errors when trying the cards. What happened?

First of all, you have to judge whether the room card chip you bought is the same model as the original factory card chip. If it is not the same model, the software will definitely not recognize it, and will prompt you to write the card incorrectly, or put the card on the card issuing machine without any sound. Even if there is a sound, the system will prompt the illegal card.

Secondly, if it is the same model, the card needs to be initialized before entering the hotel room card system. Generally, the supplier will encrypt the card before handing it over to the customer after leaving the factory (the customer doesn't know it in advance), on the one hand, in order to increase the cost of purchasing the card for the customer and earn more profits. On the other hand, it is to set a threshold for the third party to enter.

Finally, I would like to remind you that before making a room card for customers, you must determine the model of the card and provide a sample card for customers to test. Otherwise, the finished card cannot be used, which will not only delay customers' time, but also cause unnecessary losses to themselves.
