MANGO® TrusTag is a NFC Smart Tag redefining and securing interactions between people, products and organizations.

This NFC solution gives a secure, verifiable and automatic access to web content using any mobile device equipped with Near-Field-Communication (NFC) antenna. This secure access opens many fields of applications such as Product Authentification, database login to restricted group of persons as well as cloud access for selected co-workers, students,…

How does the MANGO® TrusTag work? Tap your smartphone or tablet to a MANGO® TrusTag and then the unforgeable authentication is launched: The smartphone sends to the web server a crypto-ID dynamically computed (AES-128 cryptography) and unique number for each transaction. If Crypto-ID authenticity and uniqueness is verified, access is granted to the defined web page.

Authentication Characteristics

MANGO® TrusTag is a NFC FORUM Tag Type 4 enabling a secure Crypto-ID to NDEF URI.

The Crypto-ID is an AES-128 encrypted message readable by any NFC compatible device.

Crypto-ID is sent to the server (URI address stored in NDEF) and decrypted by a PHP module installed on this server. It is an open platform, non proprietary and flexible for customization.

In addition to authentication, dynamic Crypto-ID decryption prevents replay-attacks.

Data base history verification permits to ensure Crypto-ID uniqueness and one-time use URI.

MANGO® TrusTag allows to increase security level by adding a pin code function and/or finger print identification.
