--------------------------------------------------

EM4100/4102 unique is the most widely used RFID technique. The card are great solution for access control, time attendance systems.We provide the Blank ISO card with excellent surface for after printing, as well as the Per-Printed card with offset/ silk-screen printing.
The ISO Card is optional with magnetic stripe.

The main features of the EM4100/EM4102 are:
- Function: Read Only
- Memory: 64bit Read only memory (10HEX serial number)
- Frequency: 125KHz
- RF protocol: N/A
- Modulation: ASK Manchester coding
--------------------------------------------------

 

The T5567 is a contactless R/W IDentification IC (IDIC) for applications in the 125KHz frequency range. A single coil, connected to the chip, serves as the IC's power supply and bi-directional communication interface. The antenna and chip together form a transponder or tag. The on-chip 330-bit EEPROM (10 blocks, 33 bits each) can be read and written block-wise from a reader. Block 0 is reserved for setting the operation modes of the T5557 tag. Block 7 may contain password to prevent unauthorized writing. Data is transmitted from the IDIC using load modulation. This is achieved by damping the RF field  with a resistive load between the two terminals Coil 1 and Coil 2. The IC receives and decodes 100% amplitude modulated (OOK) pulse interval encoded bit streams from the base station or reader.

The main features are:
- Contactless Read/Write Data Transmission
- Operating frequency: 100- 150KHz
- Small size, configurable for ISO11784/ 785 compatibility
- 330bit memory
- Dimension: CR80 (86mm*54mm*0.82mm)
- PVC or PET material, be available with offset printing, silk-screen printing
- Made into other shapes: keychain, tags, clamshell card, etc.
