QR-Bills gem for implementing Swiss payments.

Notes

Please note that no checks are performed to validate IBAN and references (like Creditor Reference) when submitting the params. These checks are required to be performed by the application.

Installation

Gem installation

gem install qr-bills

• Rubygems > qr-bills

Locales / Translations

Usage

Generate a creditor reference (ISO-11649) number

The creditor reference is composed as follow:

• RF + 2 check digits + reference

Max reference length is 21 chars.

QRBills.create_creditor_reference("MTR81UUWZYO48NY55NP3")
# => "RF89MTR81UUWZYO48NY55NP3"

Availables outputs formats

params[:output_params][:format] = "html"
# OR
params[:output_params][:format] = "qrcode_png"

• html returns a full qr-bill as a html-template string
• qrcode_png returns the qrcode of the qr-bill

Availables qr-bill types formats

QR bill with (new) creditor reference

This is a new bill type introduced with the new qr bills format

params[:bill_type]                      = QRBills.get_qrbill_with_creditor_reference_type
params[:bill_params][:reference_type]   = "SCOR" # fixed type for bill with creditor reference
params[:bill_params][:reference]        = "RF89MTR81UUWZYO48NY55NP3" # example

QR bill with (old) reference type

This can be compared to the (old) orange bill type

params[:bill_type]                      = QRBills.get_qrbill_with_qr_reference_type
params[:bill_params][:reference_type]   = "QRR" # fixed type for bill with qr reference
params[:bill_params][:reference]        = "00 00037 01588 13258 31366 09972" # example

QR bill without reference

This can be compared to the (old) red bill type

params[:bill_type]                      = QRBills.get_qrbill_without_reference_type
params[:bill_params][:reference_type]   = "NON" # fixed type for bill without reference

Generate a QR-Bill

# get the QR params, so you will get the full hash structure and as well some default values
params = QRBills.get_qr_params

# fill the params, for example
params[:bill_type]                                      = QRBills.get_qrbill_with_creditor_reference_type

params[:bill_params][:creditor][:address][:town]        = "Lugano"
params[:bill_params][:creditor][:address][:country]     = "CH"
params[:bill_params][:amount]                           = 12345.15
params[:bill_params][:currency]                         = "CHF"
params[:bill_params][:debtor][:address][:type]          = "S"
params[:bill_params][:debtor][:address][:name]          = "Foobar Barfoot"
params[:bill_params][:debtor][:address][:line1]         = "Via cantonale"
params[:bill_params][:debtor][:address][:line2]         = "25"
params[:bill_params][:debtor][:address][:postal_code]   = "3001"
params[:bill_params][:debtor][:address][:town]          = "Comano"
params[:bill_params][:debtor][:address][:country]       = "CH"
# you can get the new creditor reference using QRBills.create_creditor_reference("your_reference") 
params[:bill_params][:reference]                        = "RF89MTR81UUWZYO48NY55NP3" 
params[:bill_params][:reference_type]                   = "SCOR"
params[:bill_params][:additionally_information]         = "pagamento riparazione monopattino"

# generate the QR Bill
bill = QRBills.generate(params)

# bill format is given in the params, default is html
# bill has the following format:
#    bill = {
#      params: params,
#      output: "output"
#    }
