Tenants

Tenants will book their rooms on any booking platform and will start using Adderra as soon as they check-in the hotel or other rental accommodation and they can stop using it as soon as they check-out. In order, to start using this application, tenants will have to scan a QR code and fill in short but necessary information. Adderra will help them use the precious resources for which they have paid.

Resources

Resources are being paid for in advance. This is the purpose of Adderra, prepayment solution for hotels and any other rental accommodation. Tenant will be able to calculate and decide what amount of electricity or water he or she is planning to use while renting accommodation. Tenant balances the money and the meters allow the electricity and water to be available in the room. Also, as soon as the balance equals to zero, the meter will automatically stop and the utilities will stop as well. Of course, before that, tenants will receive a notification in advance in order to avoid inconvenience and discomfort.
