Recheck

*** WHAT IS RECHECK ***

RECHECK gives the opportunity to brands to digitally engrave/mark their product as
authentic and enables end-users to assure that the products they buy are original and with
proven identity. To provide maximum independence and security of the service RECHECK
uses blockchain technology to store product identity data, ownership records ,
guarantee information, etc. This ensures that customers who bought products carrying
RECHECK tag will be able to prove ownership and product identity independently, without
the need of a centralized service.

*** FEATURES ***

RECHECK aims to provide 3-levels deep verification service - production, ownership,
aftermarket. Buyers can verify the authenticity of a product, they can claim ownership and
they can transfer the ownership in case of selling the item second-hand. At each of these
steps the item can be checked against the ownership and identity data on the
blockchain . Additionally, producers can encode guarantee parameters, which can reduce
the paperwork hassle for both the consumer and the producer. Each brand has the option to
introduce gamification and customer feedback, thus receiving independent from the retail
network feedback.

*** USER EXPERIENCE ***

The target users of RECHECK are premium buyers who own a smartphone. RECHECK is a
mobile application with very simple to use interface. The only thing that users need to do
when verifying the identity of a product is to s can the QR code on the tag, or to tap on the
NFC area (optional). The application then displays the status of the verification. When users
purchase a product, they can claim ownership by entering a secret code attached to the
RECHECK tag. At that point the code is no more needed and can be removed.

*** HOW IT WORKS ***

RECHECK incorporates QR code, identity code and a secret code , protected and backed
by the Ethereum blockchain . As an option, the tag may utilize NFC as means of quick and
reliable identity check. Anytime anyone can check the availability and authenticity of certain
product.

*** LEVELS OF PROTECTION ***

The RECHECK tag is protected visually, on the level of physical integrity and
cryptographically. Customers can always check if a tag was “used” by checking a
self-destructive holographic sticker that keeps the folded parts together. Additionally, the
secret code is protected by a scratch-zone, so any attempt to unveil the secret code is
visually recognizable. And finally, the identity code is verifiable on the blockchain, but at the
same time not extractable from the blockchain (one-way hashing).
