EM4450 EM4550 chip CARD

The EM4450/EM4550 is a CMOS integrated circuit intended for use in electronic Read/Write RF Transponders. The difference between EM4450 and EM4550 is that EM4550 are bumped and has megapads for the two coils. The chip contains 1 KBit of EEPROM which can be configured by the user, allowing a write inhibited area, a read protected area, and a read area output continuously at power on. The memory can be secured by using the 32 bit password for all write and read protected operations. The password can be updated, but never read. The fixed code serial number and device identification are laser programmed making every chip unique.

The EM4450/EM4550 will transmit data to the transceiver by modulating the amplitude of the electromagnetic field, and receive data and commands in a similar way. Simple commands will enable to write EEPROM, to update the password, to read a specific memory area, and to reset the logic.

The coil of the tuned circuit is the only external component required, all remaining functions are integrated in the chip.

What is difference between EM4100 and EM4102 ISO card?

In terms of electrical function, there is no difference between EM4100 and EM4102. Both RFID chips work at 125 KHz and with 64 bit RO (read only) memory size. The major difference is that EM4102 chip has gold bumps on the die, and because of this reason coil (antenna) can be directly connected to the die.

EM 4100 die is first packed in a lead frame IC module then connected to the coil. The thickness of lead frame IC module is about 0.4mm. For EM 4102 as shown on Figure 6.2, the coil is directly connected (direct bonding) to EM 4102 die. The thickness of die is about 0.2mm only and in order to do direct bonding task we have to use thinner coil. In short, EM 4100 card needs to embed thicker coil and lead frame IC module.

Since EM 4102 ISO card does not need lead frame IC module and use thinner coil so the card surface will be much flatter than EM 4100 ISO card. The flatter card surface means better printing quality especially when using dye-sublimation printer.

THE CONTACT/CONTACTLESS ADVANTAGE

THE CONTACT/CONTACTLESS ADVANTAGE
Contact and Contactless cards are plastic identification cards containing electronic memory and, in some cases, an embedded integrated circuit (known as chip cards). They are also sometimes called “smart ID cards” or “RFID cards” depending on the type of card and the smart card vendor.

Security conscious industries (like the medical profession) utilize smart cards to enhance patient privacy and prevent fraud. Smart cards are also able to provide strong security authentication for single sign-on (SSO) in large organizations, as well as identification, authentication, application processing and data storage. Through the use of smart cards, governments and regional authorities are able to reduce budgets tied to expensive processing, and security costs associated with standard license and identification cards.

Advantages of Contactless Cards

Contactless cards house an integrated circuit chip. They provide not only memory capacity, but computational capability as well. The self-containment of a contactless smart card makes it resistant to attack, as it does not depend upon potentially vulnerable external resources. Because of this characteristic, contactless smart cards are often used in different applications which require strong security protection and authentication. For added security, a contactless smart card can be paired with a mobile phone to restrict contactless transactions when the mobile device is not within range, preventing use of the card if stolen.

RFID Smart Card
Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves. An RFID system consists of an antenna and a transceiver, which read the radio frequency and transfer the information to a processing device, as well as a transponder (or tag), which is an integrated circuit on the plastic smart card containing the radio frequency circuitry and information to be transmitted. A subtype of RFID is NFC, which stands for near field communication, enabling two devices to communicate within a very short range. NFC cards add a layer of security to information transactions.

Applications
Smart card applications include: financial, identification, SIM card, public transit, computer security, school operations, healthcare and more.

Contactless IC Card

The Contactless card range consists of read-only low-frequency ID cards, MIFARE® cards, TypeB cards and CPU cards.
These cards are used for a variety of purposes e.g. identification and electronic wallet etc. As the transmission of power and data requires no physical contact with the card, users can truly enjoy the ease-of-use of contactless technology. No longer do users have to worry about damage during card contact with readers or stains on contact surfaces that may hinder data transmission.

Contactless IC Card Advantages:
Reliable
As there is no physical contact between card and reader, previous causes for failure e.g. bad reader/card
contacts are significantly minimized
Easy & fast operation
Eliminates the need to insert and retrieve cards from readers, therefore ensuring more user-friendliness.
This product can work within a 10cm distance from the card reader.
This product also works well regardless of orientation or card reader position.
Capable of Multiple Applications
Its special memory structure enables multiple applications to run on this card. It can also run on a variety of systems. Users can define their own code and access condition for each application respectively.
Excellent Authentication and Security
A unique serial number is assigned and written into each card during its manufacturing phase. This serial
number can never be changed after the card leaves the factory.
A mutual validation standard is adopted between card and reader, meaning, the reader needs to verify the
card and the card needs to verify the reader before any transmission can begin.

Contactless IC Card Uses :
Identification
Finance and electronic money
Public transportation
Smart building
Community logistics
Social security and related fields

Contact Card
