TagInfo is a second application brought to you by NXP Semiconductors, leveraging Near Field Communication (NFC) technology. As a co-developer of NFC, NXP Semiconductors not only serves professionals but also aims to provide tools and applications for everyday users. We are enthusiastic about helping you uncover the NFC capabilities of your devices and enjoy this technology.

Main features include:

- A function to check the balance for various public transport systems

- Identification of applications present on cards and tags

- Recognition of integrated circuit (IC) types and manufacturers

- Extraction and examination of NFC data sets (NDEF messages)

- Complete tag memory layout reading and display

- Support for various NFC Forum record types (please inform us if you notice any gaps)

- Exploration of details concerning contactless cards, tags, and NFC-enabled items

- Assistance for developers in identifying configuration issues on contactless cards

- An easy and economical way to analyze contactless cards

- A broad array of user interface and application configurations

- Generation and sharing of analysis reports

The TagInfo app enables you to browse through the contents of public transport and payment cards that utilize NFC-compatible contactless technology on your device.

Some of the supported applications are:

- CLIPPER card for transportation in San Francisco Bay Area, CA, USA

- Kiev Metro in Kiev, Ukraine

- ORCA card for the Puget Sound region, WA, USA

- OV-chipkaart, public transport chip card in the Netherlands

- Oyster electronic ticketing system in Greater London area, UK (note that some cards may not allow public access)

- Myki in Victoria, Australia

- Moscow Metro in Russia

- Nol Silver and Gold Card in Dubai, UAE

- Octopus card in Hong Kong, China

- Suica card in Japan

- T:kort, Kolumbuskort, NSB-kort, Ruter Reisekortet in Norway

…and more. We are actively working to support additional card schemes as application owners and system providers share information about accessing content on their contactless cards.

Beyond its value-checking feature, TagInfo can identify many other applications such as:

- Electronic Identity Documents

- ExpressPay, a contactless payment option from American Express

- PayPass, a contactless payment product from MasterCard

- payWave, a contactless payment solution from Visa

- Zip, a contactless card from Discover Network

…among others.

It is important to note that due to the security mechanisms inherent in these applications, our app does not provide access to the actual contained data.

In addition to consumer-focused features, it thoroughly investigates publicly accessible information regarding contactless cards, tags, and NFC-enabled items. It provides details such as:

- IC manufacturer

- IC type

- Card operating system (if applicable)

- NFC data sets (NDEF messages)

- IC memory size and configuration

- Supported technologies and standards

Moreover, it facilitates complete browsing and analysis of all four NFC Forum Tag Types, along with all MIFARE-based, NTAG-based, and ICODE-based systems. Its compatibility extends beyond just NXP Semiconductors products, covering a wide array of widely deployed items that use NFC-enabled and compatible contactless technologies globally.

This comprehensive functionality and user-friendly design transform an NFC-enabled device into a potent handheld analyzer for hobbyists exploring NFC capabilities, as well as for professionals diagnosing configuration errors and data formatting issues.
