Mifare RFID Classic card

The Mifare Classic RFID card is fundamentally just a memory storage device, where the memory is divided into segments and blocks with simple security mechanisms for access control. They are ASIC based and have limited computational power. Thanks to their reliability and low cost, these cards are widely used for electronic wallet, access control, corporate ID cards, transportation or stadium ticketing.

The Mifare Classic 1k offers 1024 bytes of data storage, split into 16 sectors; each sector is protected by two different keys, called A and B. They can be programmed for operations like reading, writing, increasing value blocks, etc. Mifare Classic 4k offers 4096 bytes split into forty sectors, of which 32 are same size as in the 1K with eight more that are quadruple size sectors. Mifare Classic mini offers 320 bytes split into five sectors. For each of these card types, 16 bytes per sector are reserved for the keys and access conditions and can not normally be used for user data. Also, the very first 16 bytes contain the serial number of the card and certain other manufacturer data and are read only. That brings the net storage capacity of these cards down to 752 bytes for Classic 1k, 3440 bytes for Classic 4k, and 224 bytes for Mini.

The simplicity of the basic cards means that they are inexpensive, which is largely the reason for their success in large-scale deployments.

What is the difference between a fixed and mobile RFID reader?

What is the difference between a fixed and mobile RFID reader?
Fixed readers are set up to create and sometimes control access to secured safe zones, parking lots, certain doors, secured room, and track movement of tagged object across certain zones. Mobile readers are portable, which may be hand-held or mounted within a truck. They are commonly used by personnel to identify tagged objects or commit inventory counts of merchandise.

How do I know which frequency is right for my application?

How do I know which frequency is right for my application?
Different radio wave frequencies are used for different applications. Low-frequency tags are cheaper, use less power and are better in penetrating non-metallic substances. Hence, they are great for scanning objects with high-water content, such as fruit, at close range. Tags with higher frequencies offer better range and faster data transfer. However, they use more power and are weak in penetrating materials, which means they more commonly require a direct clear path between the tag and reader.



RFID Wet Inlays are described as “wet” due to their adhesive backing, so they are essentially industrial RFID stickers. Passive RFID Tags are comprised of two parts: an integrated circuit for storing and processing information and an antenna for receiving and transmitting the signal. They have no internal power supply. RFID Wet Inlays are best for applications where a low-cost “peel-and-stick” tag is needed. Any RFID Wet Inlay can also be converted into a paper or synthetic face label.



Radio Identification, or RFID (stands for Radio Frequency Identification) is a technology allowing to identify and characterise an object thanks to a sticker broadcasting radio waves.

RFID is part of Real Time Localisation Systems (RTLS) and is widely used for logistical purposes in many different sectors where tracking merchandises is a key issue: retailing, health, transport and logistics, military activities, etc.

Thus, NFC is derived from RFID but is different in many ways. One of the main differences is the fact that NFC allows a limited data sharing between the tag and the reader. Then, another one is that NFC has a really short range compared to RFID (a few centimeters versus a few meters).

Printing Cards

Printing Cards

All Plastic Cards and Smart Cards can be printed with 4 color, 1 color printing on 1 side or 2 sides.
This process refers to cards printed at their time of manufacture. All cards of a manufacturing batch will be printed with the same artwork/design etc.

Cards are generally manufactured using four large sheets of PVC plastic that are bonded together under a lamination (heat and pressure) process. In the first step of manufacturing the design for the face of the card is printed on one sheet and the reverse on another making up the core.

The printing of these sheets is done in volume using either a two or five colour press printing up to 35 cards per sheet. The print may be applied by silkscreen print, offset print or a combination of these depending on the requirements of your design.

Once the core has been printed, the final two layers of transparent plastic are attached and laminated in order to protect the printed surface. The cards are punched from each sheet and additional features such as signature panels, magnetic stripes, foils and holograms are added.

Offset printing
Generally Offset printing is very good at printing detail (such as small fonts and fine objects).
It is advised to use Offset Printing where you use screened layouts or four colours (CMYK). With Offset printing colours are less brilliant than Silkscreen printing.

Silkscreen printing
This process should be used for extensive layout elements, because more ink is applied to the printing sheet. This gives a more vibrant feel to the artwork. The disadvantage of more ink is that with bleeding, fine layout elements may disappear, and the printing looks less precise.

Bleeding layouts
Bleeding layouts should generally be printed silkscreen, at least those colours touching the card’s border. Of course, this is only possible if the colours are not screened or CMYK printed. On occasions it might be better to separate one colour, that is, to use Offset printing for the fine or screened elements and Silkscreen printing for the more extensive elements which have to be printed with this colour.

The reason for this lies in the different consistency of the inks : Silkscreen inks can easily be laminated due to their high share of resins and varnishes, where as the Offset inks cannot be laminated with the PVC material. Should we wish to print cards with bleeding Offset colours a special overlay foil has to be used. This overlay has a coating of glue to allow the overlay to adhere to the card. However this layer of glue may impact the colours, especially colours based on blue, purple, green or grey. With these colours we advise using silkscreen printing to improve results.

What is the Application of RFID Active Tag in Parking?

What is the Application of RFID Active Tag in Parking?
Radio Frequency Identification (RFID) is one of the fastest growing technologies used in numerous industries including supply chain management, healthcare, aviation and logistics. RFID systems use proprietary protocols and application-specific hardware. An RFID-enabled parking system will minimize the need of parking managers and employees to manually look at the parking lot. RFID tag has the ability to receive occupancy data like the number of cars entering & exiting instantly. This information and data is extremely helpful in determining the exact parking space captured and helps the respective management to take proper staffing decisions. Additionally, it will record all the entries and exits automatically & precisely that will result in least errors by human intervention.

RFID tags can also identify and monitor any suspicious and untagged vehicle present in the parking lot. CCTV cameras are generally used with RFID system to ensure 100% security from theft. For larger parking lots, RFID systems manage multiple zones to ensure complete safety of the parking facility. Thus, RFID technology (tags) is more beneficial and reliable as compared to the others in many ways as:
* RFID tags do not require any kind of physical contact between the communication device and data carrier.
* They are extremely durable; have the ability to withstand extreme temperatures.
* These tags come in vast array of sizes, materials and types.
* They have the ability to generate precise results with least errors.
* These tags can be used repeatedly that makes them much economical to use.
* RFID tags are read by the RFID system sequentially.

Whenever an RFID-labeled vehicle enters into a parking lot, the RFID system can automatically detect whether it is registered into the database or not. If it’s a registered vehicle as per the RFID database and has not checked out of an unauthorized RFID-enabled parking lot, the system will record it immediately. The RFID system records vehicle information, parking-lot title as well as entrance time and date in the ‘vehiclecirculationinfo’ table of its database. The check-in and check-out information are cross-checked by the RFID system and so, if any vehicle has attempted for an unauthorized exit, it won’t be able to enter to any of the RFID-enabled parking lots. To the vehicle-owner, the final and only solution would be to pay the fine and receive the approval to enter; from the respective authorities.

Thus, an RFID tag for parking lots will offer improved customer experience. It will ensure complete safety & security of the vehicles along with the minimized expenses of hiring staff. The integration of surveillance cameras with RFID system will help curbing the criminal attempts & offences, if any.


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.

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

Card Introduction

Card Introduction
When we use the term “card technologies“, what do we mean? The easy answer is – any technology that can be placed on a card. What is a card? Typically we think of our credit or bank card but there are other sizes and materials used for different applications. The card can be made of plastic (polyester, pvc, or some other material) or paper, card, or even some amalgamation of materials. The common point is that the card is used to provide “access” to something and it includes some form of AIDC (Automatic Identification and Data Capture) technology.

There are currently three main technologies we think of when we mention card technologies. These are magnetic stripe, smart cards, and optical cards. Other technologies can be put on cards as well (such as bar codes, touch memory, etc.). Often the card will have printing on it which may involve technologies such as Dye Diffusion Thermal Transfer (D2T2) direct to card printing.

The History
Cards have been with us for a long time, especially if you use the broader definition of what a card is. When you start to talk about “our industry”, there are a few dates that may be of interest.
