The Benefits of an RFID Key Reader

Radio frequency identification, or RFID, has been in the news a lot recently because of its use in key cards and hotel room access systems. It’s a great technology that has many benefits, but it’s not the perfect solution for every application.

Choosing the right RFID reader is important. The first thing to consider is the connector type. The rule of thumb is that opposite connector types connect.


The cost of an RFID reader depends on a number of factors. For example, some readers require a special antenna to work, which can add to the price. Other factors include the number of tags required, the type of tag and its programming, and the system’s installation costs.

RFID keys have a small chip that stores a unique code, which it transmits to the reader via radio waves. If the signal matches the correct code, the reader will open the door. The process is quick and convenient, as compared to fumbling around with a physical key. The cards are also programmable and can be programmed to open specific doors or only for a limited time.

Unlike magnetic key cards, RFID keys are difficult to copy or hack. They can only be copied by a device that has the proper software and specialized hardware. This is a major benefit of this technology, as it increases security and convenience for employees and customers.


Using radio signals, long range RFID systems communicate with tags. The reader sends out a query signal, and the tag responds with a radio signal that holds the required information. This signal is then analyzed by the reader, which determines the appropriate follow-up action. These actions can include granting access to gated areas or tracking the location of vehicles and their drivers.

The maximum read range of a particular RFID tag is listed on its manufacturer’s spec sheet. However, these values may be misleading because real-world conditions often impact the tag’s performance.

It is important to know how to optimize your RFID system’s read range. For example, the polarity of the antenna can have a significant impact on the tag’s maximum read range. This is because if the tag’s polarity doesn’t match up with the reader’s polarity, its read range will be shortened. This can be prevented by matching up the polarity of the reader and tag.


Unlike traditional keys, RFID tags don’t need to be within direct line of sight to be read. They can be scanned from a distance and even through a thick object or surface. This feature makes them ideal for use in applications like warehousing, inventory management and material tracking.

In addition, many RFID systems are able to be integrated with IP security cameras. This can help reduce manual rekeying and lockdown times by creating visual records of each time the device is interacted with. This can also help prevent unauthorized access and theft by providing clear evidence of a breach or attempt.

If you’re a commercial property owner, you may want to consider using an RFID security system to increase building and community security. These systems can help you work more efficiently, reduce costly rekeying and procurement costs, and ensure that only authorized tenants have access to your facility or vehicle. They can also help you keep track of leased vehicles and equipment more effectively.


When it comes to security, RFID systems are highly effective. They can be used to grant access to a door without the need for keying or mechanical locks. Plus, they can be reprogrammed easily.

The system consists of two parts: the RFID reader and the RFID card or fob. The card or fob contains a microchip that holds a unique ID number and an antenna that can send and receive signals. These signals can be either low or high frequency. The low-frequency RFID cards that are commonly used to access amenities and the front door into an apartment unit operate at 125 kHz.

The RF signal is transmitted through an antenna, which can be either integrated into the RFID reader or external. The antenna converts the reader’s RF signal into the magnetic field required by RFID tags to transmit data. The antenna is connected to the reader with a cable that can vary in length depending on the installation.
