Banksys N.V. (or Banksys SA) was a Belgian payment processor owned by Belgian banks.

[1] It was formed in 1989 through the merge of ATM/POS networks of Bancontact and Mister cash.

The Belgian antitrust authority noted that Banksys was too dominant in the market for payment services.

[2] The Union of Self-Employed Entrepreneurs noted in 2003 that this issue has not been fixed.

[3] Banksys was merged with Atos Worldline at the end of 2006, together with the Bank Card Company.
