A very simple implementation of the EPC069-12 Standard, also known as Girocode.

Girocodes are basically SEPA Bank Transfers encoded in a standardized message format that is machine readable and can be encoded into QR-Codes. This is very handy for users of mobile banking apps, who can just scan the QR-Code and directly have all transaction details without typing all the details.

go get github.com/scusi/epc

cd $GOSRC/github.com/scusi/epc
go build ./

The lib contains 3 example programs that show how to use the lib in a program. The following sections describe how to build and use these example programs.

cd $GOSRC/github.com/scusi/epc
go build ./cmd/epc-simple
go build ./cmd/epc-parse

epc-simple can output the EPC message as Text or as QR-Code as a PNG file.

With the following command you can create a new EPC message.

$ ./epc-simple -i "DE53200400600200400600" -n "Bündnis Entwicklung Hilft" \
	-a 5 -s "ARD/ Nothilfe Ukraine" -b "COBADEFFXXX" -format text 
BCD
002
1
SCT
COBADEFFXXX
Bündnis Entwicklung Hilft
DE53200400600200400600
EUR5


ARD/ Nothilfe Ukraine

Basically you can pipe the above command to qrencode to manually create a EPC-QR-Code from the message.

$ ./epc-simple -i "DE53200400600200400600" -n "Bündnis Entwicklung Hilft" \
	-a 5 -s "ARD/ Nothilfe Ukraine" -b "COBADEFFXXX" -format text\
	| qrencode -l H -t PNG -o images/test-qr.png 

The above command would write a new QR-Code into the file images/test-qr.png.

In order to create a new EPC-QR-Code you can do the follwoing:

$ ./epc-simple -i "DE53200400600200400600" -n "Bündnis Entwicklung Hilft" \
	-a 5 -s "ARD/ Nothilfe Ukraine" -b "COBADEFFXXX" -format png > images/test-qr2.png 

The above command would write a new QR-Code into the file images/test-qr2.png.

You can also do the reverse and parse a text format EPC message into a EPC datastructure.

$ ./epc-simple -i "DE53200400600200400600" -n "Bündnis Entwicklung Hilft" \
        -a 5 -s "ARD/ Nothilfe Ukraine" -b "COBADEFFXXX" -format text > test.epc
$ ./epc-parse -f test.epc

The first command from the above example does create a new EPC Message, in Text format and pipes that to a file called test.epc The second command reads test.epc and parses the content into a EPC datastruct (epc.EPC), before writeing it to STDOUT.
