Are you familiar with what a 125kHz card is? It has a unique type of card that aids anyone to enter through or use someof the different things. This article will explain what 125kHz cards are, along with their pros and cons, how to choose the right card according to your needs, security measures that help them stay safe, and where 125kHz cards are used.
125 kHz card is a plastic card, which contains a chip and an antenna embedded in it. This little chip is essential because it is what sends out the signals from the card. When the card is held near a special device known as a reader, it emits a low radio wave. The reader picks up this signal. It has a unique number, one used by each different card. Let’s say the reader receives some signal, this checks this number against if the card is authorized to gain entrance to a certain place or use something special. This processes occur very quickly and can easily be accessed.
Always a positive note, 125kHz cards are extremely convenient to utilize. All you have to do is bring the card close to the reader, and voilà! Also, these cards can retain things safely. These can offer a great deal of security, meaning that only those with proper authority are allowed into restricted areas or have access to secured equipment. Access control keys are also much cheaper than other types of access systems, which makes them a popular option for many individuals.
But, there are also a few cons to be considered. For instance 125kHz cards are relatively easy to clone. This means that if someone wanted, he could create a false card that would look like the original. If someone is to lose their card or have it stolen, that person could get into trouble. A lost or stolen card could allow someone else entry into places they shouldn’t be able to access. This means it's vital to look after your card and to immediately report any lost or stolen cards.
Next, take a look at how far the card can work. Some 125kHz cards are made to operate only up to short distance, ideal for access control systems that are used to open a door. Others can operate from greater distances, which is helpful in large areas such as parking lots or outdoor gates where it may be desirable not to approach too closely to the reader. Last but not least, consider the card’s security features. Some cards have additional security features, such as encryption, making them more difficult to duplicate or clone.
Before getting into the types of cards, let's briefly outline the security features we can expect from those 125kHz cards to prevent hacking. The first safety feature is the special ID number that is assigned to every card. The number is significant to be because it is fixed and non - copyable and keeps card secure. The chip in some cards is also equipped with encryption. That means that if someone attempts to duplicate the card they'll have a far more challenging task doing that. In addition, certain cards come equipped with additional security measures such as biometric scans that rely on fingerprints, or PIN codes that offer enhanced security.
125kHz cards are widely used around the world in a number of applications. Access control systems are by far the most common use case; access control systems play a significant role in securing buildings and rooms by controlling access. 125kHz cards are widely used in payment systems. These systems let people make-enable contactless payments that are significantly quicker and more comfortable to use than cash or credit cards. Lastly, the transportation system utilizes 125kHz cards to grant access to buses, trains, and other vehicles, opening up the world for everyone.
