GINKAN Inc. (GINKAN Co., Ltd.) is a Japanese fintech company founded in December 2015 and headquartered in Ginza, Chuo City, Tokyo 104-0061, Chuo-ku, Tokyo, Japan. Led by CEO Tomochika Kamiya, the company focuses on building a food and beverage ecosystem through blockchain technology and tokenomic models. Its core product, SynchroLife, is the world's first-of-its-kind restaurant recommendation platform where users earn cryptocurrency tokens (SynchroCoin, SYC) by eating out and posting restaurant reviews. As of June 2020, SynchroLife has accumulated 210,000 user reviews and more than 100,000 restaurant information, covering the whole of Japan. In September 2023, Yinkan transferred the SynchroLife business to livedoor Co., Ltd., which may mark the company's strategic adjustment.

The company has participated in projects such as Plug and Play Japan (2018) and Mitsubishi UFJ Financial Group (MUFG) Digital Accelerator (2019), and has won several industry awards, including the 2018 Plug and Play Japan "Best Domestic Fintech Company Award" and the 2019 MUFG Digital Accelerator Award.

As a fintech company involved in cryptocurrency, Regulatory Information Bank is required to comply with the Payment Services Act of the Financial Services Agency (FSA) of Japan, which regulates funds transfer services and crypto-asset-related businesses. SynchroCoin (SYC) is a utility token that rewards users and pays for food and beverages, and may be subject to the FSA's crypto asset regulatory requirements. However, the public information does not disclose the specific regulatory number or official filing information of the bank. The company ensures transaction transparency and traceability through blockchain technology, complies with Japan's Personal Information Protection Act (APPI), and protects user data privacy.

Bank's compliance measures include managing token distribution and trading through smart contracts to reduce the risk of fraud. In March 2024, Yinkan announced an innovative patent announcement that integrates payment data with NFT information to enhance compliance and data transparency. The specific Know Your Customer (KYC) or Anti-Money Laundering (AML) processes are not disclosed in detail. Due to Japan's strict regulation of cryptocurrencies, Yinkan may face ongoing compliance review.

★ Trading
ProductsInstead of directly offering traditional financial trading products, Silver Magazine supports cryptocurrency-based food service transactions through the SynchroLife platform. Core trading categories include:

1. SynchroCoin(SYC).: A blockchain-based cryptocurrency (ERC-20 standard) where users earn SYC for dining and posting reviews, which can be redeemed for restaurant coupons, gift cards, or paid for food and beverages. SYC was listed on the LATOKEN Exchange in September 2018 (LATOKEN Listing).

2. Restaurant services: Users can search for restaurants, reserve seats, and participate in incentive activities through the platform.

3. SyFu Web3 Wallet: Launched in 2024, it supports the integration of payment data and NFTs, and explores the GameFi application (SyFu Beta Launch).

As of April 2022, SYC is available in more than 570,000 locations, including brands such as Doutor Coffee, Komeda Coffee and KFC, with undisclosed transaction volume data.

★ Trading Software
