ISO/IEC 15693 is an RFID standard at 13.56 MHz in the HF (high-frequency) range, and it applies to contactless vicinity tags and readers. Manufacturers refer to it as ISO 15693 or RFID ISO 15693. The main advantage of ISO 15693 is its greater read range compared to ISO 14443 proximity cards.
Usually, ISO 15693 tags are passive and powered by the magnetic field generated by the reader. Another feature of the ISO 15693 protocol is its support for anti-collision, enabling the reader to detect a number of tags in one RF field.
In this guide, we will explore what it is, what it can do, and how it can help you improve your operations. By the end, you’ll know why ISO15693 is a game changer for RFID applications.
What is ISO15693?
RFID technology is a global standard ISO15693. Operating at 13.56 MHz the technology is sometimes referred to as the ‘vicinity card’ standard. This is because it has greater scanning range than any other RFID standard.
This standard provides manufacturers consistency. ISO15693 is the reliable and flexible solution whether you are setting up a new system or upgrading an existing one. If you need a reliable RFID solution, it’s perfect for you.
ISO 15693 Key Specifications
The ISO 15693 standard operates using magnetic coupling between the reader and tag antennas. There are three major parts to it:
- ISO/IEC 15693-1:2018– Physical Characteristics
- ISO/IEC 15693-2:2019– Air Interface and Initialization
- ISO/IEC 15693-3:2026– Anticollision and Transmission Protocol
ISO 15693 read range is dependent on the reader, antenna, tag, and installation. Mobile phones have a limited reading range, whereas desktop and industrial readers operate at larger distances with the proper antenna configuration. Factors affecting the read range include the size of the antenna, power of the reader, placement of the tag, surface material, metals, and liquids.
ISO 15693 UID and Memory Structure
The UID on the ISO 15693 chip is 64 bits long, or 8 bytes, and is programmed into each chip. It helps the reader recognize the tag and address commands. User memory can be used to store an asset number, part number, or product code, or you can keep this information in your software linked to the UID.
User memory is segmented into blocks, where size and capacity rely on the chip manufacturer. Other ISO 15693 fields include:
- AFI –filters tags based on application groups
- DSFID –provides information regarding data format
- IC Reference –provides information regarding the chip
Different readers and SDKs can interpret the UID differently in terms of byte order. Pick one for your system to maintain consistency in the records. The UID identifies the tag but doesn’t verify the authenticity of the object.
Common ISO 15693 Commands
Mandatory Commands
Two mandatory commands for ISO 15693 are Inventory and Stay Quiet. The Inventory command locates tags in the RF field and retrieves UID information. The Stay Quiet command asks one particular tag not to respond to the Inventory command so that the reader can locate other tags nearby.
Common Optional Commands
Optional commands manage memory and tag operation. The common optional commands are:
- Read Single Block
- Write Single Block
- Lock Block
- Read Multiple Blocks
- Write Multiple Blocks
- Select
- Reset to Ready
- Get System Information
Each optional function is specific to the tag and reader devices. Both the tag and the reader should have the capability to process such a command if it’s used in the system.
Extended Commands
Tags with large capacity can implement extended commands with extended block addresses. The extended commands provide access to memory beyond the 0 to 255 block range, so both the reader and SDK should support extended addressing.
Manufacturer-Specific Commands
The chip manufacturer can implement commands for EAS operation, privacy, counter operations, and other functions specific to chips. Manufacturer-specific commands are specific to a particular IC, so the reader should support the particular functions of the selected IC.
How Does ISO 15693 Anticollision Work?
Anticollision enables the reader to separate some tags within one RF field. Under a 1-slot scheme, matching tags respond in the same time slot, resulting in a collision of several responses. When using a 16-slot scheme, tags distribute their responses over 16 slots, allowing the reader to have several opportunities to recognize them.
In a toolbox that contains 12 tagged tools, the reader can detect which tools are there without individually reading them. It’s fit for small tag populations. For large and quick inventories, use UHF RFID.
Is ISO 15693 the Same as NFC Type 5?
No. They each have different responsibilities. ISO 15693 specifies the RF interface between the tag and the reader, NFC-V includes the ISO 15693 communication protocol in NFC devices, while NFC Forum Type 5 defines the storage and access of NFC data like the NDEF records.
For launching a URL NFC operation, the tag requires Type 5 formatting and NDEF data. However, other ISO 15693 tags can also communicate with phones that support them using their applications.
Typical ISO 15693 Applications
Library and Document Management
Libraries used ISO 15693 to identify several books or documents without tapping them. Small labels go into books and documents, and readers include desktop, shelf, and gate-type readers to identify checkouts and movements. Metal shelves affect the RF field, and the antenna location must be based on the shelf design.
Industrial Automation and WIP Tracking
ISO 15693 is used in controlled production facilities for trays, carriers, parts, and other workpieces. Industrial, embedded, or rugged tags connect the item to a job number or production record, with fixed readers on machines and transfer points. Make sure that the read zone is small enough to eliminate other pieces.
Tool, Mold and Equipment Management
Tools, molds, gauges, and fixtures in cabinets used ISO 15693 and work areas. Disc, PCB, embedded, and ruggedized tags are good choices for those assets, as readers can be fixed for cabinets and handheld for inspections. Choose the appropriate tag construction relying on the mounting surface and conduct tests in the final location.
Healthcare and Laboratory Samples
ISO 15693 connects tubes, trays, kits, and containers with digital information. Labels or encapsulated tags will work with desktop, fixed, and handheld readers on laboratory benches and in storage areas. If you deal with liquids, cold storage, chemical storage, or metal racks, test the tag on the actual container.
Asset Management and Smart Cabinets
ISO 15693 technology is used to identify smart cabinet tagged assets in a controlled environment. Labels should be thin for plastic assets, and rugged tags should be used for tools, laptops, and equipment. The readers and antennas in the cabinet need to separate read zones.
Reusable Containers and Metal Assets
Reusable bins, boxes, cases, tools, and equipment can apply ISO 15693 in fixed locations or in handheld reading. While non-metallic surfaces use adhesive labels, metallic assets require on-metal or ferrite-backed tags. Perform a test on the tag using the actual asset, as the metal type, content, and attachment location impact reading distance.
Product Authentication and Anti-Counterfeiting
ISO 15693 enables the link of a product with a database record, as some chips provide security features for enhanced authentication. The label or tag is selected based on the product type, space, and level of security. The reader should support the security features of the chip, because the UID is simply an identifier of the tag.
Smart Packaging and Consumer Engagement
NFC Type 5 tags based on ISO 15693 allow for the connection of packaging to URLs, information, instructions, or service history. Thin labels are used on paper and plastic, but metal and foil require special tags. NFC Type 5 tags will be supported by compatible NFC-enabled phones for consumer applications, while ISO 15693 readers support production and programming.
How to Select an ISO 15693 Tag
Tag requirements are defined first by the item and reading zone, prior to chip type and series. Identify:
- surface mounting
- available tag size
- desired reading range
- amount of memory
- quantity of tags in the reading zone
- operating temperature range
- exposure to water or chemicals
- NFC Type 5 requirement
- password or AES functions
- EAS or tamper functions
- tag printing/encoding
Some chip series families include NXP ICODE, ST25TV/ST25DV, and TI Tag-it HF-I. The amount of memory, NFC capabilities, security functions, and interfaces varies depending on the actual chip part number.
The antenna, housing, adhesive, ferrite layer, and surface mounting are additional elements influencing radio performance. Perform tests with the completed tag on the planned item.
How to Select an ISO 15693 Reader
Find the ISO/IEC 15693 standard on the list of protocols supported by the reader. Devices supporting NFC might also support the same RF protocol as NFC-V.
Compare:
- target read distance
- antenna size and number of ports
- single-tag or multiple-tag reading capability
- optional, extended, and chip-specific commands
- connection via USB, UART, RS232, RS485, or Ethernet
- connection via PLC or Modbus
- SDK and API
- supported operating systems
- temperature and IP ratings
Fixed desktop and industrial readers might support the same protocol but be used in different read areas. But, the reader should be compatible with the antenna, host interface, commands, and chosen chip.
ISO 15693 Security and Privacy
ISO 15693 has features for ID, addressing, CRC error detection, AFI, DSFID, and memory locking. ISO/IEC 15693-3:2026 also provides optional security capabilities associated with ISO/IEC 29167 cryptographic packages.
The type of security capabilities depends on the IC. Based on the particular IC used, security features might be provided for authentication, secure messaging, passwords, digital signatures, privacy capabilities, memory protection, counters, EAS, or tampering.
Protection is provided by the application. The use of basic asset identification involves fewer security capabilities than product authentication and anti-counterfeiting.
What is the difference between ISO15693 and ISO14443?
ISO15693 and ISO14443 operate at the same frequency. But their applications are very different. ISO14443 is intended for close range tasks such as contactless payments with a range of about 10 cm.
