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.

Why you don’t need an RFID-blocking wallet

Because I’m a computer security guy, I have friends who like to show off their new RFID-blocking wallets and purses. “Look what I got for Christmas!” they say. My lack of response should be telling, but they don’t seem to pick up on it.

They’ve seen the TV ads about malicious hackers who can “stand on any street corner” and wirelessly steal their credit card and other identity information. I’ve seen similar demonstrations at Black Hat and other computer security conferences for nearly a decade now. They never fail to wow the audience.

An entire, multi-billion-dollar RFID-blocking industry has emerged. You can get RFID blocking for almost any object you own. Some of my friends have so much faith in RFID-blocking products that they buy expensive, customized purses and wallets. These are the same people who drive extra miles to save a few cents on gas.

The RFID fallacy

RFID technologies have been around for a long time, and they’re now included in more and more items. Yes, your RFID products can possibly be read from a distance. Yes, a hacker might be able to read your credit card information remotely as you pass by. But before you buy an RFID-blocking product, ask yourself if you’re worrying about the right things.

First and foremost, does your credit card actually have an RFID transmitter? The vast majority does not. Have you ever been told you can hold up your credit card to a wireless payment terminal, and without inserting your card, pay for something? For most of my friends, and the world in general, the answer is no.

Most RFID-enabled credit cards are heavily marketed as capable of being used wirelessly. They have names that imply wireless payment: PayPass, Blink, PayWave, Express Pay, and so on. Usually they bear a little RFID/contactless payment logo.

Hint: The new little golden metallic square on your new credit card does not indicate RFID. Also, many new contactless payment cards will have chip-and-PIN protection — or will use the chip to securely protect even RFID communications.

If you look at the number of credit cards with RFID, you can’t even represent it statistically. It’s not 0 percent, but it’s so far below 1 percent that it might as well be 0 percent. Part of the problem is that every major credit card vendor came out with its own version, so vendors and merchants had to physically support the same standards. Most people don’t want to have to figure out which vendors support which wireless cards and go get that specific card type.

On top of that, most of the world is going to wireless payments using your mobile device. Apple Pay had more users and adopters in its first day in the market than all active users of RFID credit card products combined. Apple Pay works with every credit card you have, as long as your vendor supports Apple Pay. Did I mention that Apple Pay is far more secure in almost every way?

RFID cards are coming with chip-and-PIN protections, and the lessons learned from Apple Pay (and other mobile phone wireless payment solutions) are migrating to credit cards. The days when a bad guy can sit on a corner and sniff your credit card information out of thin air are numbered.

Entertainment for the paranoid

But did that bad guy ever sit on the corner in the first place? Sure, I’ve seen the demos, but I’ve yet to hear of one criminal who was caught using an RFID sniffer or who admitted to stealing credit card info wirelessly. We know about all sorts of cyber crime. Why not the theft of RFID credit card information if the risk is so high?

Here’s why: It would be a lousy use of a criminal mastermind’s time. Today’s smart criminals break into websites and steal hundreds of thousands to tens of millions of credit cards at a time. Why would a criminal go to the effort and expense of stealing credit card info one card at a time when you can steal a million in one shot?

If a criminal wants a credit card or even your specific credit card, he or she can buy it for a few bucks from several places on the Internet. In fact, it’s significantly cheaper than buying all the necessary RFID attack equipment and sitting in a public square (which is likely to have one or more security cameras trained on it these days).

Still worried? If you actually have an RFID-enabled credit card, it turns out aluminum foil does the same job, if not better, than an expensive RFID-blocking sleeve. I know I’m going to get email from RFID-blocking vendors saying their products protect better than aluminum foil. No doubt that’s true in some cases.

But if you’re worried about that, you should also be wrapping your car keys in aluminum foil. Now we’re in the paranoid zone. I’ve heard from readers who have — I’m not making this up — removed every electronic product in their house due to hacking fears. They’ve sold their new cars with embedded computers and gone back to older models without any. I can’t tell if I’m dealing with regular paranoid people or true paranoid schizophrenics.

If you have a credit card, there’s a huge risk it will be hacked, but not by a guy sitting on a corner sniffing for your card as you walk by. The former is a fact of life. In the latter case, you might have a better chance of winning the lottery.

Card Customization Options

Embossing: It is the process of creating a three-dimensional image or design in paper and other ductile materials. It is typically accomplished with a combination of heat and pressure on the paper. This is achieved by using a metal die (female) usually made of brass and a counter die (male) that fit together and actually squeeze the fibers of the substrate.

Hot-stamping: It is defined as a dry printing process, which uses controlled heat, pressure, and precision timing to transfer a color pigment from foil to surfaces of varied shapes and materials. This process forms a permanent bond between the part and the foil, and creates a dry print.

Hologram: A three dimensional image; unlike regular images which are usually two dimensional, a three dimensional image or hologram, appears to “pop out” of the media which it is printed on or illuminated from. Hologram images are usually created by using a single laser beam which is split and splashed onto the object and finally onto the film.

Barcode: It is an optical machine-readable representation of data. Originally, bar codes represented data in the widths (lines) and the spacings of parallel lines and may be referred to as linear or 1D (1 dimensional) barcodes or symbologies. But they also come in patterns of squares, dots, hexagons and other geometric patterns within images termed 2D (2 dimensional) matrix codes or symbologies. In spite of there being no bars, 2D systems are generally referred to as barcodes as well.
Magnetic strip: A stripe of magnetic information that is affixed to the back of a plastic credit or debit card. This stripe contains customer and account information that is required to complete electronic financial transactions. The physical and magnetic characteristics of this stripe are specified in the International Organization for Standardization standards 7810, 7811 and 7813.
Signature panel: the area of an identification card in which the bearer enters his signature (defined in ISO 7810).

Photo printing
Inkjet printing: A group of dot matrix printing technologies, such as thermal, piezo, phase change and continuous flow in which electrically charged droplets of ink are projected onto the paper or canvas.

Thermal printing: An printing method that uses heat and pressure to melt a coloured wax foil onto self adhesive vinyl.

Scratch off: A scratch-off card (also called a scratch off, scratch ticket, scratcher, scratchie, scratch-it, scratch game, scratch-and-win or instant game) is a small token, usually made of cardboard, where one or more areas contain concealed information: they are covered by a substance (usually latex) that cannot be seen through, but can be scratched off.

Offset printing: It is a commonly used printing technique where the inked image is transferred (or “offset”) from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat (planographic) image carrier on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a water-based film (called “fountain solution”), keeping the non-printing areas ink-free.

Silkscreen printing: It is a printing technique that uses a woven mesh to support an ink blocking stencil. The attached stencil forms open areas of mesh that transfer ink as a sharp-edged image onto a substrate. A roller or squeegee is moved across the screen stencil forcing or pumping ink past the threads of the woven mesh in the open areas. Silkscreen printing is also a stencil method of print making in which a design is imposed on a screen of silk or other fine mesh, with blank areas coated with an impermeable substance, and ink is forced through the mesh onto the printing surface. It is also known as “silk screening” or “serigraphy”.

what is EMV?

EMV stands for Europay, MasterCard and Visa, a global standard for inter-operation of integrated circuit cards and IC card capable point of sale terminals and automated teller machines, for authenticating credit and debit card transactions.

It is a joint effort initially conceived between Europay, MasterCard and Visa to ensure the security and global interoperability of chip based payment cards. Europay International SA was absorbed into MasterCard in 2002. The standard is now defined and managed by the public corporation EMVCo LLC. JCB joined the organization in December 2004, and American Express joined in February 2009. In May 2013 China UnionPay was announced as its latest member with UnionPay now having an equal 1/5 interest in the standards body along with Visa, MasterCard, American Express and JCB. IC card systems based on the EMV specification are being phased in across the world, under names such as “IC Credit” and “Chip and PIN”.

The EMV standards define the interaction at the physical, electrical, data and application levels between IC cards and IC card processing devices for financial transactions. There are standards based on ISO/IEC 7816 for contact cards, and standards based on ISO/IEC 14443 for contactless cards.

RFID Vs Contactless Smart cards

The debate between RFID and smart cards technology is an ongoing one. There is no clear definition that describes RFID and smart cards, and at times these two terms are used interchangeably, due to lack of awareness, resulting in confusion between the differences.

Confusion is especially strong between contactless smart cards and RFID. The key issue that has given rise to this debate is the contact less interface and that too an RF (radio frequency) one. Both contactless smart cards and RFID use radio frequencies for communicating between the card and reader. The applications for which RF is used can be different for RFID and smartcards. RFID is mainly meant for applications within the supply chain, for track and trace. Contactless smart cards on the other hand are mainly meant for payments/banking, mass transit, government and ID, and access control.

RFID and smart cards both can be used in transit applications and most of the time they are used together to provide increased convenience to end users. An example of this would be the “Touch n go” cards in Malaysia used on toll ways. The Touch n Go card is a contactless smart card, but this card can be purchased with an additional RFID transponder (where the smart card will be inserted) so that the toll booth reader can read the cards from a greater distance than the 10cm limit restricted by smart card standards. Without the additional RFID transponder, the contactless Touch n Go smart cards can still be used, which means that the driver need to screen down their windshield to tap the card on the reader, instead of just driving through while the RFID transponder will be detected by the reader above the toll booths at a greater distance.

Gift Card

A gift card is a restricted monetary equivalent or scrip that is issued by retailers or banks to be used as an alternative to a non-monetary gift.

A gift card may resemble a credit card. The card is identified by a specific number or code, not usually with an individual name, and thus could be used by anybody. They are backed by an on-line electronic system for authorization. Some gift cards can be reloaded by payment and can be used thus multiple times.

Cards may have a barcode or magnetic strip, which is read by an electronic credit card machine. Many cards have no value until they are sold, at which time the cashier enters the amount which the customer wishes to put on the card. This amount is rarely stored on the card but is instead noted in the store’s database, which is cross linked to the card ID. Gift cards thus are generally not stored-value cards as used in many public transport systems or library photocopiers, where a simplified system (with no network) stores the value only on the card itself. To thwart counterfeiting, the data is encrypted. The magnetic strip is also often placed differently than on credit cards, so they cannot be read or written with standard equipment. Other gift cards may have a set value and need to be activated by calling a specific number.

gift cards can also be custom tailored to meet specific needs. By adding a custom message or name on the front of the card, it can make for an individualized gift or incentive to an employee to show how greatly they are appreciated.

Gift cards are divided into “open loop” or “network” cards and “closed loop” cards. The former are issued by banks or credit card companies and can be redeemed by different establishments, the latter by a specific store or restaurant and can be only redeemed by the issuing provider. The latter, however, tend to have fewer problems with card value decay and fees. In either case the giver would buy the gift card and the recipient of the card would use the value of the card at a later transaction. A third form is the “hybrid closed loop” card where the issuer has bundled a number of closed loop cards; an example is a gift card for a specific mall.
