What's New in TrainOS
1.4.0
September 8, 2026
- Pay at the front desk: Academies can now take card payments in person with a card reader. Memberships, store orders, and one-off charges all go through the same flow, and you get the same receipt you would paying in the app - Save your card at the desk: Tap or insert your card once on the reader and, with your permission, your academy can keep it on file, so renewals and store pickups do not need it again - Card readers, for staff: Set up and manage readers from Payments — connect one, give it a name, and see which are online. At checkout you pick the reader, follow the charge on screen, and can retry or cancel without leaving the sheet - Saving a member's card, for staff: Collect it on the reader or type the details in by hand; either way it becomes their default for future charges
