I -suggested using vCard field definition, to get some standard format -for name and address, but any format would work. I did not do -anything about the proposal, but hoped someone one day would make -something like it. It would make it possible to efficiently send -machine readable invoices directly between seller and buyer.</p> - -<p>This was the background when I came across a proposal and -specification from the web based accounting and invoicing supplier -<a href="http://www.visma.com/">Visma</a> in Sweden called -<a href="http://usingqr.com/">UsingQR</a>. Their PDF invoices contain -a QR code with the key information of the invoice in JSON format. -This is the typical content of a QR code following the UsingQR -specification (based on a real world example, some numbers replaced to -get a more bogus entry). I've reformatted the JSON to make it easier -to read. Normally this is all on one long line:</p> - -<p><img src="http://people.skolelinux.org/pere/blog/images/2016-03-19-qr-invoice.png" align="right"><pre> -{ - "vh":500.00, - "vm":0, - "vl":0, - "uqr":1, - "tp":1, - "nme":"Din Leverandør", - "cc":"NO", - "cid":"997912345 MVA", - "iref":"12300001", - "idt":"20151022", - "ddt":"20151105", - "due":2500.0000, - "cur":"NOK", - "pt":"BBAN", - "acc":"17202612345", - "bc":"BIENNOK1", - "adr":"0313 OSLO" -} -</pre></p> - -</p>The interpretation of the fields can be found in the -<a href="http://usingqr.com/wp-content/uploads/2014/06/UsingQR_specification1.pdf">format -specification</a> (revision 2 from june 2014). The format seem to -have most of the information needed to handle accounting and payment -of invoices, at least the fields I have needed so far here in -Norway.</p> - -<p>Unfortunately, the site and document do not mention anything about -the patent, trademark and copyright status of the format and the -specification. Because of this, I asked the people behind it back in -November to clarify. Ann-Christine Savlid (ann-christine.savlid (at) -visma.com) replied that Visma had not applied for patent or trademark -protection for this format, and that there were no copyright based -usage limitations for the format. I urged her to make sure this was -explicitly written on the web pages and in the specification, but -unfortunately this has not happened yet. So I guess if there is -submarine patents, hidden trademarks or a will to sue for copyright -infringements, those starting to use the UsingQR format might be at -risk, but if this happen there is some legal defense in the fact that -the people behind the format claimed it was safe to do so. At least -with patents, there is always -<a href="http://www.paperspecs.com/paper-news/beware-the-qr-code-patent-trap/">a -chance of getting sued...</a></p> - -<p>I also asked if they planned to maintain the format in an -independent standard organization to give others more confidence that -they would participate in the standardization process on equal terms -with Visma, but they had no immediate plans for this. Their plan was -to work with banks to try to get more users of the format, and -evaluate the way forward if the format proved to be popular. I hope -they conclude that using an open standard organisation like -<a href="http://www.ietf.org/">IETF</a> is the correct place to -maintain such specification.</p> - -<p><strong>Update 2016-03-20</strong>: Via Twitter I became aware of -<a href="https://news.ycombinator.com/item?id=11319492">some comments -about this blog post</a> that had several useful links and references to -similar systems. In the Czech republic, the Czech Banking Association -standard #26, with short name SPAYD, uses QR codes with payment -information. More information is available from the Wikipedia page on -<a href="https://en.wikipedia.org/wiki/Short_Payment_Descriptor">Short -Payment Descriptor</a>. And in Germany, there is a system named -<a href="http://www.bezahlcode.de/">BezahlCode</a>, -(<a href="http://www.bezahlcode.de/wp-content/uploads/BezahlCode_TechDok.pdf">specification -v1.8 2013-12-05 available as PDF</a>), which uses QR codes with -URL-like formatting using "bank:" as the URI schema/protocol to -provide the payment information. There is also the -<a href="http://www.ferd-net.de/front_content.php?idcat=231">ZUGFeRD</a> -file format that perhaps could be transfered using QR codes, but I am -not sure if it is done already. Last, in Bolivia there are reports -that tax information since november 2014 need to be printed in QR -format on invoices. I have not been able to track down a -specification for this format, because of my limited language skill -sets.</p> - - -
