+## Inspiration
+The Mobile payments market in China is exploding.
+
+The payment apps and QR codes in retailers and other offline businesses have become ubiquitous in China, young consumers rarely carry a wallet or cash. In 2015 Chinese citizens transacted $1 trillion through mobile payments using QR codes. In 2017 it was $15.5 trillion. In 2020 it is forecast that Chinese consumers will transact $45 trillion through mobile payments, by which time the county will be pretty much cashless.
+
+Solutions like WeChat Pay and Alipay are:
+- Highly Centralized
+- A Chinese Bank account is needed
+- Not available for foreigners
+- Highly censored
+
+The 27 Oct 2018 China ruled that China’s Merchants are Legally Allowed to Accept Bitcoin and Crypto.
+
+## What it does
+xPay is an open alternative to mobile payment point of sale.
+
+💲 Everything in dollars (DAI)
+⚡️ Fast transactions (5s confirmation)
+🔑 Secure, no keys are stored in the POS, the connected wallet is used in watch mode.
+
+## How we built it
+xDAI chain, web3, react-native, Blockscout explorer API
+
+## Challenges we ran into
+web3 1.0 beta works badly with react-native, had to switch to previous version.
+
+## Accomplishments that we're proud of
+The proof of concept is fully functional.
+
+## What we learned
+xDAI Chain opens scenarios for real use cases for the local economy.
+
+## What's next for xPay
+- Integration with Inventory Management Software
+- Automated Accounting
+- Record gift cards, and other forms of tender
+- Send and track invoices from your device 
+- Apply discounts and issue refunds
+- Send receipts via email or text message
+- Access real-time sales data and complete sales history
+- Track inventory in real time
+- Connect a receipt printer, kitchen ticket printer, bar code scanner, and cash drawer
