The authenticity of Sofroniev shoes is protected with the modern blockchain technology that is a symbol of security and traceability. This is the technology behind electronic money, such as Bitcoin, Ethereum and more.
In the box of your shoes you will find a warranty card on which is attached a small electronic tag with ReCheck logo. This tag is a round sticker and contains a NFC chip with programmed unique identifiers that you can verify using your smartphone. All you need to do is download the free ReCheck mobile application from App Store or Google Play and tap your smartphone on the NFC chip to scan it and make sure you have bought original Sofroniev shoes.
