Printed RFID cards


Custom Printed RFID Cards

RFID cards are being more widely used in a variety of industries, including merchants, nightclubs, restaurants, hotels, clubs and associations, wholesalers, schools, libraries, and colleges, among others. These RFID cards make it possible to control the venue and maintain security in specific sections, and they're simple to use for personnel.

How Do RFID Cards Work?

RFID stands for "radio-frequency identification," and it works by attaching labels or tags to specific identifying objects. It's usually a credit card-sized card with little transmitter-receivers on it. These radio transmitters are two-way, which means they can both broadcast and receive information. Readers or interrogators are radio functions that send an immediate signal to the tag and read the response that is received back.

An RFID card consists of several components: an integrated circuit that allows information processing and storage, a radio frequency signal that may be modulated and demodulated, an incident reader signal that supplies DC power, and an antenna that transmits and receives the signal. In addition, the tag information is saved in a memory storage component. RFID tags typically use either a chip-wired logic or a pre-programmed or programmable data processor to sensor and transmit data.

The matching RFID reader sends out an encoded radio signal that interrogates the card. When the card receives a message from the reader, it sends back a message including the identity information as well as any other relevant data. The tag's unique serial number, a batch or lot number, the stock number, the manufacture date, or any other special information programmed on the card are normally included in this return transmission.

If the physical features characterize the RFID card as a separate entity from the RFID tag, the RFID card's technological attributes distinguish it from other card shape items.

Simply said, each RFID card contains an antenna that is coupled to an RFID IC, allowing it to receive, store, and transmit data through radio waves. RFID cards typically use passive RFID technology, which means they don't have an internal power source. The electromagnetic energy received and delivered by the RFID reader powers the RFID card.

Based on the difference in frequency, RFID cards are divided into four kinds.

RFID card with a reading distance of 1-2cm and a low frequency of 125KHz.

RFID card with a reading distance of up to 10cm and a high frequency of 13.56MHz.

RFID card with an ultra-high frequency of 860-960MHz and a reading distance of 1-20 meters.

Two or even three distinct frequencies can be combined onto a single RFID card.

Why custom printed RFID card from us ?

DO RFID Group is an RFID card maker that specializes in custom printed RFID cards. Please review the list below to discover what printed RFID we can make for you.

Printed RFID card with Offset Printing technology 

In the modern plastic card manufacturing sector, offset printing is the most widely utilized technology. It begins with the creation of offset printing plates for each color (CMYK / Pantone) from a digital source (computer to plate—CTP). A laser beam is used to expose the image to the light-sensitive plates. The plates are affixed to the Offset machine's printing cylinders, which are rotated against water and ink rollers. The ink rollers soak the graphic portion of the plate with ink, while the water rollers soak the non-graphic parts of the plate with water. The plate next transfers the ink to a second cylinder's rubber blanket, which offsets the picture onto the PVC sheet that runs between it and an impression cylinder. The UV curing mechanism dries the ink on the PVC sheet very instantly.

We have four Heidelberg Speedmaster printers that print five colors and one Heidelberg Printmaster printer that prints four colors, so we never have to compromise for poor color matching or print defects just to keep the line running. Every order is printed on independent printing plates, and colors are matched to CMYK/Pantone or prior sample cards, as well as confirmed with a color spectrometer and physical swatches.

Printed RFID card with Silk Screen Printing technology

Another method for printing RFID cards is to utilize a permeable woven cloth stretched over a frame. For the negative sections of a picture, a stencil is generated on the screen by filling its mesh. The photo emulsion process is a frequent way to do this. A positive film of the image is created and placed over a light-sensitive emulsion-coated screen. The emulsion will harden in regions of the screen where UV light passes through the transparent areas of the film when exposed to ultraviolet light. After that, the non-hardened emulsion will be wiped away from the screen, leaving a negative stencil of the picture. The screen is placed over the PVC sheet to be printed and filled with ink in the press.

Screen printing can also be used to decorate printed RFID cards with metallic and effect pigment inks. We employ completely automatic Sakurai screen printers in a dust-free environment to provide a combination of high precision and productivity.

Printed RFID card with Digital Printing technology

Orders requiring extensive or sophisticated customization are printed using our latest HP Indigo digital printers, which produce high-quality output at up to 3600dpi. Printed RFID Cards can be entirely customized to be relevant to your target audience and can be adapted to specific persons or groups, regardless of whether the data is static, personalized, or segmented. Personalized advertising, automatic numbering, bar codes, alphanumeric databases, and images are some of the applications.
