After May 19, it will no longer be possible to use public transportation with the Strippenkaart (strip card) in the Province of South Holland.

Shops and supermarkets have already stopped carrying supplies, while transportation companies such as HTM and Connexxion will inform passengers that they can only pay with the OV-chipkaart and season or HTM tickets.

Note that strip cards have already been abolished in Amsterdam and Rotterdam.
