Sometime last week, I don't exactly recall when, I've read in a newspaper that parliament had decided to allocate extra funds to speed up the introduction of the public transport payment method (as it would also allow for identification and access control). So we can conclude that all small value payment methods benefit from some intervention by public authorities
- chipknip is mandatory for paying at parking meters (a local tax),
- public transport payments will be subsidized to allow quick identification,
- SMS/0900 payments are fully exempted from supervision law.
Essentially, to be succesfull, any issuer of payment instruments should thus seek endorsement of a public authority.
UPDATE: The Automatiseringsgids reported here on the same issue.
