Solo & Visa Electron

In essence, Switch/Maestro and Visa Delta are also charge cards and so there is a certain element of credit worthiness involved. However, the basic idea of carrying a card around rather than cash is universally liked.

Solo and Electron makes it possible for a new group of customers, those unable to obtain a Switch or Delta, to purchase products using plastic.

The same principle applies with purchases. The card is swiped, the account is checked, and if the required balance is present, then the transaction is authorised. With these cards, you are only able to spend the funds held in your account and no more.
