Jablotron PC-02 access tag
The Jablotron PC-02 access card is a contact-free RFID key-tag for operating the system, black.
Availability: In stock
SKU
PC-02
The PC-02 access key-tag is a proximity card, RFID standard EM UNIQUE 125kHz. Up to 50 cards can be used in the system, for higher security each card can be combined with a digital code (PIN).
Programming user access codes and PC cards
Keyboard programming: ∗6 MC nn NC
• Only programmable if the system is totally unset
• MC = Master Code or card.
• nn = user code or card position from 01 to 50.
• NC = the new code or card entry (entry by holding the key in front of the keypad).
• Factory default: all user codes and cards are erased.
• Each user position can have both a card and a code programmed to it (by using the sequence ∗6 MC nn NC twice)
• Each user code can have its own reaction programmed by an installer in Service Mode, and with a split system, codes can be assigned to different sections.
Example:
∗6 1234 12 4345 (code 4345 will be programmed to user position 12)
To erase codes/cards enter:
• ∗6 MC nn 0000 erases the code and the card in user position nn.
• ∗6 MC 00 UC erases the code UC (or card UC) if programmed to any user position.
• ∗6 MC 00 0000 erases all user codes and cards in user positions 01 to 50.

Hello, can you please explain the differences in RFiD, EM and MiFare protocols.
Thanks

MIFARE, RFID, Wiegand, and EM represent different components and technologies within the access control and identification industry. RFID is the overarching radio technology, MIFARE and EM are specific types of RFID, and Wiegand is the protocol used to communicate that data.
RFID - Radio Frequency Identification
RFID is the broad technology that uses radio waves to identify objects or people. It consists of a tag (card/fob) and a reader.
RFID allows contactless reading of data. It is divided into Low Frequency (LF), High Frequency (HF), and Ultra-High Frequency (UHF).
Key Difference: This is the umbrella term for all radio technologies.
EM Protocol (EM4100/EM4200) - 125kHz
EM cards are a popular type of 125 kHz Low-Frequency (LF) RFID tag, often called "Proximity" cards.
These cards transmit a fixed 40-bit or 64-bit ID number when placed near a reader. They are passive and do not have internal security, meaning they are very easy to clone.
Key Difference: Low cost, no data storage capacity, easily cloned, and low security. Best for basic entry.
MIFARE (NXP Semiconductors) - 13.56MHz
MIFARE is a brand of 13.56 MHz High-Frequency (HF) RFID smart cards, complying with ISO/IEC 14443A.
MIFARE cards are "smart cards" that have an embedded microcontroller and memory. They support mutual authentication (the reader authenticates the card, and vice versa).
