Conclusion.
13.56MHz RFID cards typically follow the ISO 14443 or ISO 15693 standards, which define the communication protocols between the card and the reader. These 13.56MHz RFID cards support contactless data transmission, offering relatively fast data reading and writing speeds. As a result, they are widely used in near-field communication (NFC) and electronic tagging applications, such as access control systems, payment systems, and logistics management.
13.56 MHz is a high-frequency wireless communication frequency widely used in RFID technology.
The operating principle of 13.56 MHz: communication occurs between the RFID card and the reader via an electromagnetic radio field. When the reader is close to the RFID card, the chip inside the card is activated and exchanges data with the reader using modulation and demodulation techniques. This process typically uses asynchronous communication to ensure data security and stable transmission.
1. Inductive Coupling: The 13.56 MHz wireless signal is applied to passive RFID tags through inductive coupling. When the RFID tag is within the reception range, it detects the wireless signal and harvests energy.
2. Energy Transfer: After the passive RFID tag receives energy through inductive coupling, it uses this energy to activate itself and communicate with the RFID reader.
3. Data Transfer: Once the passive RFID tag is activated, it can transmit the stored information to the RFID reader via 13.56 MHz wireless signals, enabling data reading and writing operations.
1. MIFARE Classic: Developed by NXP Semiconductors, it is widely used in various embedded systems, such as access control cards and public transportation cards. This card includes basic security mechanisms and supports data encryption.
2. MIFARE DESFire: More secure than MIFARE Classic, it supports advanced security strategies and is suitable for multiple application scenarios.
3. ISO 15693 Tags: These are more versatile and can be used with a variety of devices, commonly found in logistics and warehouse management.
High-frequency RFID technology, typically operating at the 13.56 MHz frequency band, has distinct and unique characteristics compared to low-frequency and ultra-high-frequency RFID:
1. Moderate Communication Distance:
HF RFID generally offers a communication range between 1 centimeter and 1 meter. This feature makes it excel in scenarios requiring precise close-range identification. For example, in access control systems and electronic payment applications, high-frequency RFID enables fast and accurate identity verification and data transmission.
2. Efficient Data Transmission Speed:
High-frequency RFID technology supports high-speed data transmission with stable and reliable communication between readers and tags. This characteristic gives it an advantage in scenarios requiring frequent data interactions, such as library management systems, where it can quickly update information related to book borrowing and returning.
3. Ability to Identify Multiple Tags Simultaneously:
Although high-frequency RFID may experience a certain level of interference when communicating with multiple tags at the same time, its one-to-many data transmission capability is still noteworthy. In inventory management and logistics tracking, high-frequency RFID effectively enhances work efficiency and reduces human error.
4. Strong Environmental Adaptability:
13.56MHz RFID tags have a strong resistance to environmental interference, allowing them to operate stably in various complex conditions. This makes high-frequency RFID technology highly applicable in fields such as industrial production and healthcare.
13.56 MHz means the operating frequency is 13.56 MHz. Like 2.4 GHz (gigahertz), 13.56 MHz (megahertz) is a frequency used by wireless devices. For example, devices like cordless phones and wireless routers typically operate at 2.4 GHz, while 13.56 MHz is commonly used for radio frequency identification (RFID).
RFID technology can be classified into low frequency, high frequency, and ultra-high frequency systems, depending on the frequency used. RFID products operating in different frequency bands have distinct characteristics. 13.56 MHz falls within the high-frequency range.
In free space, the wavelength (λ) of an electromagnetic wave is inversely proportional to its frequency (f). The relationship is given by the formula:
λ=c/f
where c is the speed of light, approximately 3×10^8m/s.
Calculation Process:
Substituting f=13.56×10^6Hz into the formula, the wavelength can be calculated as:
λ≈22.12meters
Therefore, the wavelength of an electromagnetic wave at 13.56 MHz is approximately 22.12 meters.

13.56 MHz RFID card vs. 125 kHz RFID card: Low-frequency (LF) and high-frequency (HF) RFID are radio frequency identification technologies that operate at different frequency ranges. They differ in terms of working principles, read/write distances, and application scenarios. The specific comparison is as follows:
If higher security and data storage capabilities are required, 13.56MHz is more suitable; while for simple identification and applications with greater environmental interference, 125KHz may have advantages. The choice of frequency should be based on actual needs.
Yes.
NFC can read 13.56MHz tags.NFC (Near Field Communication) technology operates at exactly 13.56MHz, which makes it possible to read and write tags that conform to that frequency.NFC technology is based on the development of RFID technology, inheriting the 13.56MHz frequency characteristics of RFID and therefore able to interact with tags of that frequency. NFC technology is based on the development of RFID technology and inherits the 13.56MHz frequency characteristics of RFID, so it is able to interact with tags of this frequency.
Phones can read 13.56MHz RFID tags, but whether this can be achieved depends on the hardware and software support of the phone.
Hardware Support: The NFC (Near Field Communication) function in phones typically supports 13.56MHz RFID tags, as NFC and high-frequency RFID tags operate at the same frequency. NFC technology is widely used in phones and supports three modes of operation: reader mode, card emulation mode, and peer-to-peer mode. Reader mode allows the phone to act as a reader to access information from other cards, making it feasible to read 13.56MHz RFID tags at the hardware level.
Software Support: While hardware support exists for reading 13.56MHz RFID tags, software support is key to enabling this functionality. Many phone manufacturers and software developers may not specifically design NFC reading functions for standard RFID tags, so not all phones with 13.56MHz NFC capability can read ordinary RFID tags. Users may need to find specialized applications that can utilize the phone's NFC function to read RFID tags. Some third-party applications may offer this functionality, but their compatibility and reliability can vary depending on the phone model and operating system version.
