Accepting debit or credit cards online via a PSP for any gaming, egaming, remote gambling, casino or betting site will be challenging. However, it is possible. The most important factor is you are likely to have far more success when applying for a PSP via an existing contact of the Payment Service Providers, who the PSP's know and trust. The payment provider will want to ensure chargebacks and fraud are minimal, and this is helped by robust company processes, the correct license and ongoing compliance. Companies such as Harvex have strong relationships with Gaming/Gambling PSP's, which can help support your application, both on a success rate and also on timescales.
