TEE-coin reinvents the review system with the power of cryptocurrency.


What’s TEE-coin

TEE-coin is a reward token based on cryptocurrency technology and, as an exchangeable currency to many cryptocurrencies, solves the problem of the inability to use cryptocurrencies at merchants. Faster than anything else, with low service fees, in the amount you need when you need it, we provide you with the ability to top-up TEE-coin with other cryptocurrencies and to make payments speedily.


How does TEE-coin work?


Problems Faced by Consumers

Inability to use many cryptocurrencies as a means of exchange
Limited usage of cryptocurrencies

Many cryptocurrencies exist in the world and they aim to be exchangeable with other cryptocurrencies and fiat. However the flow from cryptocurrency to withdrawal or debit card requires a significant amount of transaction time and services fees making the primary blockchain features of low cost and convenience unrealised.

Disappearing reward programs
Limitation of Rewards Programs

Merchants with their own reward programs provide a reward card unique to their shops. However, issues like loss of point cards, the expiry of the points, and a lack of attractive products to exchange for show how non liquid, inconvenient these programs are, as well as the lack of safety features of these programs.

Decision making in searching for merchants
Difficulties in searching for merchants

To search for merchants, you will need various information like the location, reviews, price, space of the shop, coupons, etc. Many users are currently using Google Maps, TripAdvisor, or Yelp. However, there are gaps and inaccuracies between the information provided and the actual information.

Problems Faced by Merchants

Acquisition of New Customers
Acquisition of New Customers

User behaviour have changed due to the diversification of information and e-commerce channels. Online sales and convenience stores are steering customers away from many merchants.

Cultivation of Repeat Customers
Establishing Repeat Customers

 The cost for acquiring a new customer is 5 times higher than that for retaining a customer. The challenge is to establish a trigger for repeated visits that can be controlled by the merchant.

Brand Building
Brand Building

Brand building requires a long-term brand awareness campaign. The key element for brand building is to collect a large number of reviews. The challenge is to aptly collect reviews from a large number of customers.

Disposal Loss
Material Waste/Loss

Material waste/loss has a direct impact on profit. It causes various problems including disposal costs and environmental issues. The key to reduce material waste/loss, is to have constant engagement and real-time communication with customers.
