Rewritable EM ID 125khz blank card with em4305 access control

Specification

EM4305 is a CMOS integrated circuit intended for use in electronic Read/ Write RF transponders. It is suitable for low cost solutions like animal tagging applications.

The main difference between the EM4205 and EM4305:

- EM4305 are bumped with enlarged pads for the two coil inputs. The enlarged bumped pads of the EM4305 transponder are intended for direct antenna connection avoiding the need of a module.

- EM4305 offers a 330pF resonant capacitor version.

The IC is powered by picking up energy from a continuous 125 kHz magnetic field via an external coil, which together with the integrated capacitor form a resonant circuit. The IC reads out data from its internal EEPROM and sends it out by switching on and off a resistive load in parallel to the coil using a large modulation index. Commands and EEPROM data updates can be executed by 100% AM modulation of the 125 kHz magnetic field.

The EM4205/4305 supports bi-phase and Manchester data encodings. The EM4205/4305 operating modes are stored in the EEPROM configuration word. All EEPROM words can be write-protected by setting protection bits. The IC contains a factory programmed 32 bit unique identifier number (UID).

Applications

Animal Identification according to ISO FDX-B

Pigeon races standard

Waste management standard (BDE)

Access Control

Time Attendance

Industrial

White Blank without printing

There is no any printing content on the blank card. Many customer order large quantity blank card.

They print the blank cards by their printer that can save a lot of cost.

Generally laminated coated overlay should be added on blank card, and then it is printable by customer.
