The cost of acquiring customers has increased by nearly 35% between 2022 and 2025, particularly for venues like restaurants, bars, clubs, and corporate event spaces. Traditional advertising channels often require significant upfront spend but provide little clarity about what truly drives results, leading to an “attribution black box.” Traditional promotional arrangements often rely on self-reported metrics, which can lead to campaigns that never deliver real value. This high-risk environment makes customer acquisition feel like a gamble rather than an investment. Belong, a Web3 community platform, has developed a zero-risk customer acquisition model called CheckIn, which uses a multi-verification system that connects QR codes, NFC technology, and geo-location to confirm physical presence. Once a referred customer makes a purchase, smart contracts automatically calculate and distribute rewards. This model eliminates common pitfalls of traditional affiliate arrangements and ensures venues only pay for actual value. CheckIn’s architecture builds on Belong’s existing geo-rewards layer, which was originally developed for the Chain Atlas project. It now extends this verification expertise to ongoing customer relationships and integrates with Belong’s upcoming LONG token. Customers who pay with LONG receive an automatic 3% discount, while venues benefit from near-instant settlement. With Belong’s established infrastructure and performance-based model, it has the potential to set a new benchmark for customer acquisition in the venue sector.
