Joys allows settling payments between Joys system participants and online or retail stores on the legal basis. We connect blockchain projects to the platform and provide integration with POS systems at sales points. This saves project teams that would like their cryptocurrency or tokens to be accepted in stores eliminates the trouble of complex, time-consuming and costly integration with POS systems. We design Joys as a tool of convergence between conventional monetary system and the new blockchain-based system to boost economy effectiveness. We expand application of cryptocurrency of any blockchain project at retail stores and service companies; this way, we involve classical retail into blockchain community and add value to both cryptocurrencies in general and currencies of projects connected to Joys independently. Projects which have their own cryptocurrency may provide the opportunity to use it at any store connected to the system. If Joys integration is in place, the project’s cryptocurrency may be used for payments. This also applies to the projects which have bonuses, a game, or an internal currency. We approach each integration individually and consider if the project has its own cryptocurrency or tokens, whether it is listed at stock exchanges, is private, etc. For this purpose, we provide Joys API access, application or website widgets, and help integrate them into the project. We perform integration into POS systems in a way that supports conventional sales business logic, so there is no need to install new POS software or hardware. When new cryptocurrencies emerge, Joys provides an opportunity to keep legacy POS systems integration solutions. To get started with Joys, it is only required to have the latest version of cash register software, conclude a contract with Joys and activate the cash register’s digital signature. In countries where payments with cryptocurrencies in stores are prohibited, we offer two processing options: use loyalty points to make partial payments for purchases (this option has been up and running), or use prepaid cards and digital coupons to make full payments for purchases (this option is currently being tested). To start using Joys, you only need to install the Joys Wallet app, open settlement wallets and deposit the cryptocurrency you intend to use for purchase payments.
