TPV - CROAT.Community

CROAT TPV

With second anniversary of CROAT the CROAT TPV has been presented. A pwa that has been created from the opinions of community users; who want to use CROAT as a means of payment. According to these users, one of the problems, as a seller, is the agility of the process of selling an item. Since, at the time of sale, even paying with CROAT, the value of the item is designed in Euros, making the conversion calculation can slow down the process.

Let us take as an example a seller in the antique market of Celrà who wants to sell a collection of football cards valued at 20€. The seller has a sign where he announces that he accepts CROAT as a payment method. A customer approaches and asks the value in CROAT of this collection. The seller has different options to know the price. One, for example, can be:

Enter the Croat.community website
Use the CROAT-Euro calculator

If the customer accepts, the seller must:

Open the wallet from the CROAT Light Wallet, also available as webapp
Validate the user and solve the CAPTCHA
Select a wallet from the list
Select "Request"
Write the value (CROAT-Euro) calculated in the previous step
Generate QR code

This logical process is what we wanted to accelerate. If we review the process with the CROAT TPV we would have:

Open CROAT TPV
Select a parity
1. Market parity: This first option refers to the current parity (CROAT-Euro) in the exchanges and CROAT TPV automatically provides in real time.
2. Personal parity: This option is made to be able to "avoid", where possible, fluctuations in the value of CROAT in exchanges. User can have a fixed parity of, for example, 1€ = 1000CROATs
3. CROAT: This last option is to be able to charge directly with CROATs. That is, the value of the collection of cards is directly advertised in (for example) 20,000 CROATs. Here, you can enter it directly.
Set the value, according to the parity option chosen
Generate QR code

In addition, with this way it is not necessary for the dispatcher to have access to the wallet of the business. Another advantage is that the CROAT TPV, as well as the CROAT Light Wallet of CROAT.Community, detects if the payment has been issued and notifies us with the transaction hash within the blockchain.

So, we review the different options below. From the initial configuration to the list of transactions.

Wizard Home QR Transactions Options

croat-tpv-assistent

When entering for the first time in https://tpv.croat.community/, first of all, a language is requested. In addition, depending on the device used to access, recommendations for installing access to the application as webapp are shown. That is, have an icon on the mobile screen to access quickly. Providing a better user experience, since it has been programmed to work better in this format.

If we already have the CROAT TPV as webapp, we open it and start the initial assistant. This helps us define different values that the application will use to work, including:

Language
The language chosen for the assistant will be saved as default in the application. Options: Catalan, Spanish and English
Wallet
This is the wallet of the seller or the business. All QR codes generated to request payments will go to this wallet. Be sure to put on the desired one.
FIAT
The fiat currency used for parities. As we do with the language, we do not limit only the changes available to the Euro. We can choose between: Euro, Dollar, Pound, Renminbi (yuan) and Ruble
Personal parity
Here, we define a parity to use that does not depend on the markets. It also shows a current value in the markets to be able to have a reference value.

With all this, we already have what it takes to start using the application.

croat-tpv-home

Once the configuration wizard is finished, the application always remains in the initial tab; indicating that the device is configured correctly. At the moment, in the current version, this screen only shows this information.

croat-tpv-qr1

In this tab we will generate the QR codes necessary to accept CROATs. At first, we must choose one of the 3 available parities:

Market parity: At the top we have the current value, we must put the value in FIAT currency and click on [Generate QR]
Personal parity: At the top we have the value of personal parity, we must put the value in FIAT currency and click on [Generate QR]
CROAT: In this option you just have to put the amount of CROATs to generate the request QR code

In all options decimals are accepted.

Once the QR code is generated, we will also have a total value ratio (FIAT / CROAT), a 10-minute countdown to complete the operation and an option to cancel it.

If all goes well, the customer can now use the CROAT Light Wallet to scan the QR code and make the payment. Once done, the TPV screen will detect the transaction, showing the hash, to indicate that it has been processed.
