Capture warranty cards through physical dataphone

We would like to propose an improvement related to the capture of warranty cards, especially when the customer is physically in the establishment.

Currently, we use Paycomet or a physical POS terminal, and when we want to save a card as a guarantee, we must request the data manually or send a link to 0€ to the customer to enter his card and tokenize it. This is especially cumbersome at reception, when the customer is already present.

Proposal:

Explore the possibility of integrating physical dataphones (I am aware that Stripe has terminals, for example) that allow:

Capture a guarantee card directly from the dataphone without the need to enter it manually or send a link making a charge authorization to 0 €, so that the card is stored as a guarantee (tokenized), and the customer has previously accepted that operation in person.

In addition, it would be ideal if this card could be reflected in the system as "captured as a guarantee", and could be used later to make charges if necessary (no show, damage, etc.), with greater legal and technical security.
