Transferring money between any payment system is easier than ever
Vizium is an advanced Android app to transfer and exchange money. It helps users to find people who want to transfer currency from one platform to another (e.g. from Payoneer to PayPal) or exchange currency. This application is aimed to provide people with a tool to exchange money quickly, stress-free, and without fees.
With Vizium users can exchange 180 currencies as well as 6 cryptocurrencies. In addition, you get to choose the people to deal with — only those with good reviews.
Vizium is a convenient alternative to unreliable currency exchange forums and bank apps that charge a commission. The key advantage of the app is that the user is the one who chooses the exchange rate.
Vizium was developed from scratch based on clear technical requirements. The LANARS team took part in polishing the app concept, studying competitors and target audience insights, designing UX and UI prototypes, as well as money exchange app development and testing. Our team also took over the publication of the application on the Google Play Market.
Product advantages
Exchange money safely — Vizium is enhanced with data encryption algorithms to ensure security of the deals, comfortable geolocation tracking for finding the best meeting venue, and many more. Discover more features of the application in the advantages section.
The user can respond to an already existing currency exchange offer if it meets their expectations. Such offers are also automatically shown to users after they have created their offers. If a user likes a currency exchange offer of another user, they request the deal. Users can also set currency price tracking and offer to monitor in their region.
Vizium is an international app. A user from any country can post their offer. Here, they indicate the currency pair, as well as the amount of money they want to exchange and the payment system that they want to use. Offers are accompanied by geotags and information in the form of exchange.
If users plan to meet for currency exchange, they must decide on their meeting point and add it to an interactive Vizium map. When both users find themselves in that location, the button to complete the deal is activated in their apps.
Each user of this app to exchange money receives ‘Likes’ for completed Deals and ‘Dislikes’ for transactions that did not take place due to their failures. The deal will be marked as failed if the user canceled it after having initially accepted, or has specified the incorrect geodata.
Challenges and solutions
Data encryption and secure data storage
Problem
Money exchange apps must use the most recent, up-to-date data encryption technology and ensure the security of user data.
Solution
Users’ info is not stored on servers and no one from Vizium or other local or foreign companies has access to it. We have applied the same principle to geolocation data. Only partners receive information about their meeting place. We also additionally verify the identity of users using their phone numbers.
Inviting people to use Vizium
Problem
Like any up-to-date on-demand service, this application can be useful only when a critical mass of users is active in it.
Solution
To attract early adopters, we've made the app free to download and commission-free.
