My FC-S02M access controller sometimes can read the card sometimes can not read the card, what is the matter?
Hello! Thank you for using our products! The first step is to check whether the power supply is working properly. The second step is to check if the card reader is damaged. The third step is to check whether there is strong magnetic interference around the card reader. If more than a few steps out, still can't read card reader, can be identified as the cause of the problem: card reader device used for a period of time will produce some electrostatic, often time accumulation caused by electricity consumption is too large, use the shorter the time such a problem that readers aging too quickly. To solve the problem: before installation should choose good quality, large power door dedicated power supply, such as using the situation after the electric lock is separated from the card reader power supply, plus a power to the card reader separate power supply. Access control card reader card read slow induction is close to the troubleshooting problems: the first step: card reader is installed on the metal The second step: whether it is in and out of the credit card, such as access to a credit card to see how much space between two card reader the cause of the problem: the card reader, such as in a metal, because the metal shielding function, card reader launch waves are part of the metal mask. In the case of swiping and swiping, the same problem occurs when the two card readers are installed too close to each other. Two card readers emit radio waves at the same time, and the interference of the radio waves will cause the reading card to be slow, and the card will not be read too close.
