Common EM RFID Chips Explained
The use of EM RFID chips in low-frequency identification systems of 125kHz is common because of their simplicity and reliability. EM4100 and EM4102 are read-only chips holding a unique ID, which is suitable in simple access control and recognition systems.
EM4200 enhances the consistency and the stability of signals and preserves the read-only functionality. EM4305 and EM4450 are compatible with read and write functions where external data may be modified, cloned, and the system can be managed flexibly.
Such writable chips are commonly used in projects which need to be reprogrammed or have advanced access control logic. All types of EM chips are used in dissimilar purpose and hence the system designers can deem cost, flexibility and functionality according to the application requirements.

Materials, Sizes, and Formats of RFID EM Cards
JLTRFID RFID EM cards come in various materials such as PVC, PP, PET and ABS to fit the durability and environmental requirements. Standard card size is CR80 at 85.5mm x 54mm which can be used with the majority of card readers and card holders.
Special applications are also supported by custom sizes. The production of the cards can be in thin, thick, or coin-style cards depending on the conditions of use. Surface finishes are white glossy, matte, full-color printing and metallic gold or silver. The diversity enables RFID EM cards to satisfy functional and branding needs in industries.
RFID 125kHz EM Cards vs 13.56MHz MIFARE Cards
RFID EM cards work at 125kHz and are meant to be used in simple and short-range identification and access control. They are ideal in simple security systems since they are fast to read, stable, and the cost of implementation is low.
Compared to this, 13.56MHz MIFARE cards offer greater data storage, encryption and multi-application capabilities on a single card. MIFARE cards are more appropriate in a setting that demands high security, payment, or data storage.
EM cards are still used when there is a legacy system and cost-sensitive deployments, whereas MIFARE cards can be used when the security level is higher and the functions are multifunctional.


EM Cards vs HID Cards
EM cards operate on open 125kHz technology and can be used on numerous access control systems. They are economical, simple to implement, and can be integrated with various systems.
HID cards are usually more expensive and with limited compatibility, in addition to being based on proprietary formats and provide greater security measures. EM cards would suit organizations that are in need of cheap and wide-range systems. HID cards can be more applicable in closed settings where the security infrastructure needs to be brand-specific.
