RFID cards are used almost everywhere. You can find these radio frequency identification or RFID cards in different industries around the world. Hospitals, libraries, manufacturing facilities, hotels, and ticketing booths are just a few of the industries that maximize this technology. They resort to RFID cards mainly for security and accuracy purposes. In this article, you will gain insight into the RFID cards’ attributes, functionality, advantages, applications, and features. You will also learn more about key factors to consider when searching for an RFID card.

What are RFID Cards

RFID card is a smart card that contains specific data. It uses radio waves to wirelessly process the information. As the RFID is scanned, the transaction is done and the operation is completed.

Physical characteristics

1. Dimensions

The dimensions of an RFID card are the same as a standard debit or credit card. This is based on the international standard ISO/IEC 7810 for the physical characteristics of an ID card. An RFID card measures 3.470 inches by 2.125 inches. In the metric system, the card has dimensions of 85.60 mm by 53.98 mm.

2. Base Material  

An RFID card is composed of three parts- the RFID chip, the RFID tag antenna, and the RFID tag substrate. The RFID chip is made of a semiconductor material where the RFID tag antenna is placed. The tag antenna is usually made of aluminum, silver, or copper. It can be integrated into the chip through etching stamping, or printing. The chip itself is integrated into a substrate. The RFID card substrate can be made of plastic, paper, or wood, depending on your preferred material. Differences in durability should be considered in choosing the type of material to be used. Sustainability is also a factor.

3. Printing & Additional Craft

Printing companies can be tapped to supply you with RFID cards as well as other types of identification, access, or proximity cards. These companies ensure compliance with standards for sizing, physical characteristics, and security requirements.

RFID Cards Based on the Difference Between Frequencies

RFID cards are differentiated based on the range of frequencies that they use to transmit data. These are the low-frequency, high-frequency, ultra-high-frequency, and dual-frequency ranges. Listed below are the most commonly utilized frequencies in each category:

1. 125KHz Low Frequency RFID Card

Low-frequency RFID cards have a shorter read range. They are mainly used for identification and access control. Other applications include livestock counting and tracking.

2. 13.56MHz High Frequency RFID Card

The high-frequency RFID cards can be used in distances of up to 1 meter. You can find these RFID cards in ticketing and payment centers. The NFC or Near Field Communication technology is a version of high-frequency RFID.

3. 860-960MHz  Ultra-High Frequency RFID Card

If you need data identification and transmission for distances of up to 12 meters, you should consider ultra-high frequency RFID cards. They are inexpensive to produce. Industries connected to inventory tracking and pharmaceutical products use UHD RFID systems.

4. Dual Frequency RFID Card

Dual frequency, as the name implies, combines two different frequency ranges on a single card. This gives you a wider range in terms of distance and usage. Limitations of using one frequency are also overcome through dual-frequency RFID cards.

The structure of RFID Card

The main components of an RFID card are the integrated chip, the antenna, and the substrate. Durability and functionality are important in the construction and assembly of RFID cards for them to work as designed.

How Do RFID Cards Work

An RFID system has three parts. It is composed of a scanning antenna, transceiver, and transponder or RFID tag. The scanning antenna and the transceiver work together to activate the RFID tag. This tag is located on the RFID card. As the RFID transponder in the tag is activated, it gives a radio signal back to the transceiver and scanning antenna to provide the information and allow access or transaction.

The Benefits of RFID Cards

Improved Security

RFID cards enhance building and road security. Access to private areas is monitored and checked through the use of RFID cards.

Enhanced Access

With the use of RFID cards, only key people can have access to rooms, buildings, and other areas of the facility. Control management is enhanced through the issuance of RFID cards. Even with the increase in employees and area, companies can efficiently manage the company premises through a robust RFID system.

More Hygienic

RFID cards offer a more hygienic solution to companies requiring a cleaner and healthier facility. Touch sensors and mechanisms for room entry can be a health hazard for healthcare. RFID cards provide a safer way of access because of the use of frequency ranges.

Secure Data

Advanced encryption is implemented on RFID systems to ensure that the data stored on the card is protected and secure. Transmission is only between the reader and the card.

Inexpensive

RFID cards are inexpensive to make. Printing companies also provide different means for you to save on each unit through material and design options.

Access and Engagement Analysis

Additional technology can be utilized with RFID to assess and analyze the data collected using the system. RFID analytics is used for streamlining processes and adjusting controls.

Personalization

Custom RFID cards are offered by printing companies. This will allow a more personalized card for promotion and marketing purposes.

More Convenient

With the interaction of RFID readers and tags, you can easily pass through any access-controlled area. It gives you less work and more time to do your activities.

More Efficient

As your company processes are being automated, your production and efficiency are also enhanced. Quicker access without delay is prioritized with the use of RFID systems.

The Applications of RFID Cards

Keep people and data secure

You can depend on RFID systems to keep people and data secure. Keeping track of personnel access while protecting data through algorithms is a main feature of RFID cards.

Used as payment cards

RFID payment cards provide a contactless method for better and faster transactions. Physical swiping is no longer needed with this technology.

Used in hospitals or other healthcare facilities

Patients, doctors, and staff are now being kept safe and illness-free with the use of RFID cards. Medication can also be tagged so that correct drug usage and dosage are monitored.

Key Factors for selecting the right RFID Card Solution

1. Security– the amount of security provided by the RFID system
2. Compatibility– compatibility with your existing technology
3. Scalability– the area covered and future plans using the same system
