Personal ov-chipkaart without iDEAL / BSN

Hi all!

In March I will come to Nijmegen for a couple of months and I planned to discover nearby cities in the weekends, therefore a Personal ov-chipkaart could be helpful for spending a bit less.

Since I don't think I will request a BSN, I don't think I would be able open a dutch bank account with iDEAL.

So, do you know if there is any alternative? Is there the possibility to request it offline? Thank you!
