Swiss DTA payment file format

Ruby library for the Swiss DTA payment file format. See for more Information.

The DTA documentation in PDF format can be found here:


Early alpha. All payments are supported. It lacks payment validations and extended documentation


gem install payment_dta --source


require 'rubygems'
require 'payment_dta'

DTAFile.create("/tmp/dta_payment.dta") do |file|
  file <<
  file <<


  • Add validations

  • Merge namespaces DTA::Payment and DTA::Payments

  • Remove duplications in payment classes

  • Document the code according to the English DTA spec

  • Add API to generate a string instead of a file so that it can be used in a web application

  • Move tests for generator from test unit to rspec

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but

    bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
