6. Payment card schemes, issuers, acquirers, processing entities and other technical service providers shall not insert automatic mechanisms, software or devices on the payment instrument or at equipment applied at the point of sale which limit the choice of payment brand or payment application, or both, by the payer or the payee when using a co-badged payment instrument.
Payees shall retain the option of installing automatic mechanisms in the equipment used at the point of sale which make a priority selection of a particular payment brand or payment application but payees shall not prevent the payer from overriding such an automatic priority selection made by the payee in its equipment for the categories of cards or related payment instruments accepted by the payee.
