What is a Swap Badge?

The Swap Badge is an NFC microchip that securely stores an item’s history, identity details, and swapp data. You attach a Swap Badge to an item to make it a Switem. It is a digital passport that allows items to be authenticated and verified. The Swap Badge is a key component of the Switems ecosystem, enabling users to track and trace the proven history of an item.

Features

  • Secure Storage: The Swap Badge securely stores an item’s history, identity details, and swapp data.
  • Authentication: The Swap Badge allows items to be authenticated and verified.
  • Traceability: The Swap Badge enables users to track and trace the proven history of an item.
  • Hubs: The Swap Badge can be used to connect with Swapps and Personas in Hubs.
  • Swapps: The Swap Badge enables digital brand-specific experiences through interactions with Switems, Personas, and Swap badges.
  • Privacy: The Swap Badge ensures the privacy and security of an item’s data. We have a special focus on privacy and security, and we are committed to protecting your data.

​
What NFC microchip is used in the Swap Badge?

We use the NTAG424DNA NFC microchip in the Swap Badge. The NTAG424DNA is a secure NFC Forum Type 4 Tag that provides state-of-the-art security features. It is designed to protect data integrity and privacy, making it ideal for secure applications such as the Swap Badge.

We get our badges from NXP Semiconductors. NXP is the world’s leading provider of secure connectivity solutions for embedded applications.

​
How does Swapnice interface with the Swap Badge?

We are the proud developers of multiple proprietary software libraries written in Swift and Java that allow us to interface with the Swap Badge. These libraries ensure smooth communication between the data stored on the Swap Badge and the Swapnice platform.

We use LRP (Leakage Resilient Primitives) to communicate with the Swap Badge. LRP is a standard protocol used to communicate with NFC tags and readers. It allows us to read and write data to the Swap Badge securely.

We also rotate the AES encryption keys on the Swap Badge to ensure the security of the data stored on it. This adds an extra layer of security to the Swap Badge, making it virtually impossible for unauthorized users to access the data stored on it.

​
What is stored on the Swap Badge?

The Swap Badge securely stores the following information on the microchip:

  • HubID: The unique identifier of the Hub associated with the item.
  • Product Name: The name of the item.
  • AES Encryption Keys: The encryption keys used to secure the data on the Swap Badge.
