How do contactless payment bracelets works?

Contactless payment bracelets contain a „Mini-NFC-Chip“ that links to the VIMpay-App. Also every „Mini-NFC-Chip“ from other providers, with the same size can be used. You can load Euro curency to the Mastercard Account from your bank account through the VIMpay App, where you can also move your money to your chip card and track all your transactions.
