NFC TagInfo by NXP 5.0.0

Are you curious about the remaining value on your contactless public transport card? Have you ever wondered about the technology behind these cards? Would you like to explore the NFC-enabled items in your possession? TagInfo is the perfect solution for you.

TagInfo, brought to you by NXP Semiconductors, is an application that utilizes Near Field Communication (NFC) technology. As co-inventors of NFC, NXP Semiconductors not only provides services for professionals but also offers utilities and apps for the general public. Our goal is to help users explore the NFC features of their devices and enjoy this technology.

Main features:

• Value checker function for select public transport systems
• Identification of applications contained on cards and tags
• IC type and IC manufacturer identification
• Extraction and analysis of NFC data sets (NDEF messages)
• Reading and display of complete tag memory layout
• Support for all kinds of NFC Forum record types
• Exploration of details related to contactless cards, tags, and NFC-enabled items
• Help for mobile developers in detecting configuration errors on contactless cards
• Easy and cost-effective analysis of contactless cards
• A wide range of user interface and application configurations
• Creation and sharing of analysis reports

The TagInfo application allows you to browse the content of public transport and payment cards that are based on contactless technology compatible with NFC on your device.

Some of the supported applications include:

• CLIPPER, all-in-one transit card system in the San Francisco Bay Area, CA, USA
• Kiev Metro card system in Kiev, Ukraine
• ORCA, a regional card for the Puget Sound region in WA, USA
• OV-chipkaart, public transport chip card in The Netherlands
• Oyster, electronic ticketing system in the Greater London area, United Kingdom (limited public access for some cards)
• Myki card system in Victoria, Australia
• Moscow Metro card system in Moscow, Russia
• Nol Silver and Gold Card systems in Dubai, UAE
• Octopus card system in Hong Kong, China
• Suica, Super Urban Intelligent Card system in Japan
• T:kort, Kolumbuskort, NSB-kort, Ruter Reisekortet card systems in Norway

We are continuously working to enable more card schemes as application owners and system providers provide information on accessing content on their contactless cards.

In addition to its value checking function, TagInfo can identify many additional applications such as:

• Electronic Identity Documents
• ExpressPay contactless payment card by American Express
• PayPass contactless payment card by MasterCard
• payWave contactless payment card by Visa
• Zip contactless payment card by Discover Network

Please note that our application does not provide access to the actual contained data due to the security mechanisms implemented in these applications.

Alongside its consumer-focused functions, TagInfo explores the full details of openly accessible information on contactless cards, tags, and NFC-enabled items. It provides information such as:

• IC manufacturer
• IC type
• Card OS (if present)
• NFC data sets (NDEF messages)
• IC memory size and configuration
• Supported technologies and standards

Furthermore, TagInfo supports browsing and analysis of all four NFC Forum Tag Types, as well as MIFARE, NTAG, and ICODE based systems. Its support is not limited to products by NXP Semiconductors but covers a wide range of the most deployed products and systems that use NFC-enabled and compatible contactless technologies worldwide.

The comprehensive coverage and ease of use make an NFC-enabled device a powerful handheld analyzer for hobbyists exploring the capabilities of NFC-enabled items and compatible devices, as well as for professionals helping them identify configuration problems and data formatting issues.
