Detailed Description of 125KHZ/13.56mhz TK4100 NTAG 213 215 216 Smart Cards

Frequency Characteristics

In the field of smart cards, 125KHZ and 13.56mhz are two important operating frequencies. The 125KHZ frequency is relatively low. The signal propagation distance is limited, but it has good penetration. It is suitable for some application scenarios where the distance requirement is not high but the ability to penetrate certain obstacles is needed, such as some short-range access control systems. The 13.56mhz frequency is higher, with a faster data transmission speed and a relatively longer signal propagation distance. It is often used in occasions that require fast data interaction, such as bus card payment systems and e-ticket systems.

TK4100 Smart Card

The TK4100 is a low-frequency smart card operating at 125KHZ. It features low cost and simple operation. The internal storage capacity of this card is relatively small. It is mainly used for some simple identity recognition scenarios, such as residential area access control cards and simple attendance systems. The coding method of the TK4100 card is relatively fixed, and the data storage security is average. However, for some applications with low security requirements, it occupies a certain market share due to its price advantage.

NTAG 213, 215, 216 Smart Cards

These three smart cards all operate at 13.56mhz and belong to high-frequency smart cards.

NTAG 213: It has a moderate storage capacity and is suitable for some applications with not particularly high data storage requirements but a need for fast reading and writing. For example, some small consumer point cards and simple electronic tags. The NTAG 213 has a fast reading and writing speed, which can meet the needs of daily fast transactions.

NTAG 215: Compared with the NTAG 213, the NTAG 215 has a larger storage capacity, which allows it to store more data information. It is suitable for scenarios that require storing more user information or complex business data, such as membership card systems, which can record members' consumption records, points, personal information, etc.

NTAG 216: Among these three, the NTAG 216 has the largest storage capacity and higher security. It uses more advanced encryption technologies to protect the stored data and is suitable for applications with high requirements for both security and data storage volume, such as small-value financial payment cards and high-security access control systems.

In conclusion, these smart cards at 125KHZ and 13.56mhz play important roles in various application scenarios with their different characteristics, meeting the diverse needs of the market.
