Use of alternative schemes
The Swiss banks are assuming that in the future billers will want to offer their customers other alternative schemes in addition to bank transfers, some of which may not yet currently exist. To design the QR code to be future-capable for this purpose, the banks have built in an "alternative scheme" element at the end of the QR code. Additional information for up to two alternative schemes can currently be filled in here.
Additional information for up to two alternative schemes can currently be filled in here. The meaning of the first characters of the "alternative scheme parameters" field is predetermined as follows:
|Characters 1-n||indicate the schemes to which the filled in parameters belong|
|Characters n+1||defines the separator with which the subsequent parameters are separated|
|From characters n+2||for the necessary alternative scheme parameter, separated by the defined separator. All parameters that may contain personal data must first be displayed, followed by the other parameters.|

Other owners of alternative schemes that would like to use the QR-bill can contact firstname.lastname@example.org to clarify the options and further schemes.
Implementation through providers of solutions for billing
During the implementation of this function, providers of software solutions must make sure that the use of alternative schemes can be managed through the master data. For each biller it must be possible to define whether, and to which schemes, this information should be sent. It is recommended that an internal solution be prepared for the use of procedures that can later be easily upgraded. If a bill recipient should receive information about a specific scheme, then the "alternative scheme parameters" field should be filled in with values according to the specifications of the scheme owner.
