MIFARE Ultralight RFID Inlay at a Glance

MIFARE Ultralight RFID inlays combine an NXP MIFARE Ultralight IC with a tuned RFID antenna and substrate for integration into labels, tickets, cards, tags and other contactless products.

The inlay operates at 13.56MHz and uses the ISO/IEC 14443 Type A interface. The exact memory, security functions and operating characteristics depend on the selected IC configuration. Finished read performance also depends on antenna design, reader configuration, product construction and the application environment.

Important: IC specifications and finished-label specifications are not interchangeable. The final operating range, temperature rating and RF performance should be confirmed for the complete inlay or label construction.

Which MIFARE Ultralight Configuration Do You Need?

“MIFARE Ultralight” describes a family of contactless IC products rather than one universal memory and security configuration.

For a new RFID project, the exact IC should be selected according to the required memory, authentication, reader commands, application logic and security requirements.

Kaisere can help confirm the appropriate inlay configuration based on your existing RFID system and application requirements.

Before production, confirm:

·Exact IC part number

·Required memory

·Reader and reader model

·Supported commands

·Authentication requirements

·Data format

·Antenna dimensions

·Finished product dimensions

·Required read performance

·Application environment

For example, MIFARE Ultralight C uses the ISO/IEC 14443 Type A interface at 13.56MHz and provides 3DES authentication, while other members of the Ultralight family have different feature sets. The exact IC specification should therefore be confirmed before production.

How Does a MIFARE Ultralight RFID Inlay Work?

A MIFARE Ultralight RFID inlay consists primarily of an RFID IC and antenna integrated into a suitable substrate or adhesive construction.

When the inlay enters the RF field of a compatible reader, the passive IC receives operating energy from the reader and communicates wirelessly using the supported contactless protocol.

The inlay can then be converted into a finished RFID label, ticket, card, tag or other contactless product.

For reliable system integration, the IC, antenna, reader, data format and final product construction should be evaluated together rather than selecting an inlay based on frequency alone.

MIFARE Ultralight RFID Inlay Applications

Access Control

MIFARE Ultralight inlays can be integrated into contactless credentials and access products where the selected IC and security configuration meet the requirements of the access-control system.

Typical formats include cards, labels, tickets, badges and customized credentials.

Before volume production, the inlay should be tested with the intended reader and access-control system.

Ticketing

Ultralight-based RFID inlays can be integrated into disposable or limited-use tickets for events, transportation and other contactless ticketing applications.

The inlay format can be customized for ticket dimensions, printing, numbering, encoding and roll-based production.

Product Authentication

RFID inlays can provide a unique electronic identity for products, packaging and labels.

Depending on the selected IC and system design, the RFID identifier can be associated with product records and checked through an appropriate reader or NFC-enabled device.

For authentication projects, the IC security features and backend verification process should be defined before production.

Loyalty Programs

MIFARE Ultralight inlays can be integrated into loyalty cards, membership products, promotional items and NFC-enabled customer credentials.

Custom printing, encoding and product formats allow the RFID component to be integrated into an existing customer-facing product.

NFC Identification

13.56MHz MIFARE Ultralight inlays can also be used in suitable NFC-enabled applications where the selected IC and system requirements are compatible.

The final NFC performance depends on antenna geometry, product dimensions, reader or smartphone configuration and the surrounding material.

Custom MIFARE Ultralight RFID Inlay Solutions

Kaisere provides customization options for RFID inlays and finished labels according to the required application and production format.

For custom antenna designs or unusual product dimensions, sample evaluation should be completed before mass production.

RFID Inlay RF Performance and Quality Testing

RF performance is influenced by more than the IC alone.

A finished RFID inlay can be affected by:

·Antenna geometry

·Antenna material

·Inlay dimensions

·Substrate

·Adhesive

·Product surface

·Reader antenna

·Reader power

·Operating environment

For this reason, Kaisere recommends testing the complete finished construction against the customer's intended reader and application.

Quality checks can include:

·IC model verification

·Antenna continuity

·Inlay dimensions

·Visual inspection

·RFID communication testing

·Read / write verification

·Encoding verification

·Printing inspection

·Adhesive and construction inspection

·Quantity and packaging inspection

Where a customer has defined acceptance criteria, the approved sample and production specification can be used as the reference for subsequent production batches.
