What is personalisation?
Personalisation is the process of issuing a bank card for a specific user in a bank personalization center. A similar process applies for the wearables, including payment rings.
To use the personalisation scheme, the bank can use existing personalisation center facilities: it does not need to be connected to the Mastercard Digital Enablement Service (MDES).
What is tokenization?
Tokenization is a process of creating a virtual card, to reduce usage risks. It replaces the PAN number of a real card with an alternative PAN number: the virtual does not disclose the details of the original card. To use the tokenization scheme, the bank should be connected to the Mastercard Digital Enablement Service (MDES).
The virtual card created is a depersonalized token that is linked to a physical card and associated to your ring. Even if the accessory is lost or stolen, your funds are safe.
Our manufacturer provides the service to issue tokens, to load them onto your ring(s) and to manage the tokens (virtual cards) and payment rings.
