RFID Cards

RFID stands for Radio Frequency IDentification.

RFID is a technology for automatic identification and data capture. With RFID, data can be stored and read on an RFID transponder (also called a chip) contactlessly and without line of sight.

The contactless systems consist of chips (e.g., as part of an RFID card, label, or tag), the reader/writer devices, and application software.

Plastic cards with RFID chips are increasingly used in areas such as access control, time tracking, ticketing, and customer loyalty. RFID chips can also be attached to objects as tags. These tagged objects can be automatically identified based on the stored data. RFID chips are also embedded in small capsules to be implanted in living beings, such as pets, for identification purposes.

Data transmission between the transponder and the RFID reader takes place via electromagnetic waves. There is a distinction between active and passive RFID technologies. The most common passive RFID technologies use an inductive magnetic field to power the chip for communication. Active transponders have their own power supply (e.g., batteries). Passive RFID chips typically communicate over only a few centimeters, whereas active transponders can cover long distances.

In automatic data capture (Auto-ID), mostly passive RFID systems are used. Typical applications include time tracking, access control, authentication, billing systems, customer loyalty, and ticketing.

Active RFID systems are usually used for the localization, identification, and navigation of vehicles and aircraft.

Passive RFID chip cards can also be divided into two frequency ranges: 125 kHz and 13.56 MHz. The best-known and most widely used RFID card types include MIFARE, HID, LEGIC, Hitag, ICode, EMxxxx (e.g., EM4102 read-only), and many more.

RFID cards are PVC plastic cards equipped with a transponder (chip) for contactless data transfer, which is not visible to the user. RFID cards are also often referred to as transponder cards or contactless chip cards.

The abbreviation RFID stands for Radio Frequency Identification. Simply translated, this means "radio identification." RFID is a technology for automatic identification and data capture.

With RFID, data can be stored and read on an RFID chip (also called a transponder) without physical contact and without line of sight. For this data exchange, an RFID card communicates with a reader device (also called an RFID reader). The data transmission between the transponder and the RFID reader takes place through electromagnetic waves.

RFID cards must first be encoded with individual data or information in order to be used for contactless applications. This can include identification numbers, access permissions, or other personalized information.

To encode an RFID card, an RFID Reader is required. The choice of RFID reader depends on the RFID chip used in the RFID card. We offer card readers for Low Frequency, High Frequency, or Ultra High Frequency chips. Some RFID writers also support multiple frequencies simultaneously.

We are happy to assist you in selecting the appropriate RFID reader. Of course, you can also entrust us with the encoding of your cards as RFID experts.

Transponder cards are used worldwide in numerous applications and have become part of everyday life. The most well-known cards with RFID or contact chips are health cards, bank cards, loyalty cards, and company IDs. Here’s a small selection of applications for contactless chip cards:

• Accreditation
• Visitor badges
• Permanent cards
• Company ID cards
• Voucher cards
• Loyalty cards
• Employee ID cards
• Membership cards
• Key cards
• Student ID cards
• Student cards
• Club membership cards
• Time tracking
• Access control
