Bank transfers are a usual way form of payment in the European regions for a one-time purchase, such as a public event. Giving this option to pay for a public event would be an enormous win for my community. This would not need to be a fully integrated piece, but rather an option that allows them to see my bank information (that I enter as part of the payment template options) which they then use when paying from their bank. I would then have the option to confirm (after I receive the transfer in my bank) the payment in HB by merely clicking a button/ticking a box indicating that this participant has paid for th event.
