1. About Bluecode

General information about Bluecode

1.1 What is Bluecode?

Bluecode is the first pan-European mobile payment solution that enables cashless payments via Android smartphone, iPhone and Apple Watch combined with value-added services in a single technology platform. In accordance with European data protection standards, no personal data is ever exchanged with participating banks or merchants thus none is stored or transmitted on the mobile phone during the payment process. The highly secure, TAN-based payment system works with all checking accounts and is independent from the transmission technology (barcode, QR code, bluetooth).

Bluecode started in 2017 in Austria. Since 2018, Alipay users have also been benefiting from a cooperation between Bluecode and Alipay. The expansion into the German market took place in the same year.

1.2 How do customers link Bluecode to their bank account?

With Bluecode there are two ways app users can link their bank account:

1. With partner banks, they can register immediately and directly in their bank’s app or online banking. This registration is particularly fast and possible at all Bluecode partner banks.

2. At all other banks, you can register using a SEPA direct debit procedure. The direct debit mandate is stored and the payment processed by SIX Payment Services Ltd. SIX is a company audited by the Financial Market Authority and one of the largest direct debit processors in the German-speaking countries.

1.3 Are there payment limits when paying with Bluecode?

For security reasons Bluecode limits the number of payments to four payments per hour and ten payments per day with a transaction limit of 400€. This may vary depending on the issuer.

1.4 How does the Bluecode QR code payment work?

Bluecode QR Code Payment is a variant of eCommerce Payment. The checkout system (merchant’s shop) produces a QR Code according to the payment data by calling a Bluecode API via 1cs OPS, and then the customer scans the QR Code with his mobile device to finish the payment.

4.2 Calling the interface for a Bluecode Website payment with QR Code (Sale)

Cancellations and credits are available for Bluecode payments as described in the sections below. Only credits are available in batch mode. For point-of-sale transactions please use connection for Bluecode QR Code payment.

Use the following URL to process an Bluecode QR Code payment via redirect to the Bluecode form: https://www.computop-paygate.com/Bluecode.aspx

Use the following URL to process an Bluecode QR Code payment via Server-to-Server connection – you have to transform the Bluecode URL into a QR Code: https://www.computop-paygate.com/BluecodeS2S.aspx

Notice: For security reasons, 1cs rejects all payment requests with formatting errors. Therefore please use the correct data type for each parameter.

The following table describes the encrypted payment request parameters:

General notes: We recommend using the parameter “response=encrypt” to receive an encrypted response from 1cs Online Payment system However, fraudster may just copy the encrypted DATA-element which are sent to URLFailure and send the DATA to URLSuccess. Therefore ensure to check the “code”-value which indicates success/failure of the action. Only a result of “code=00000000” should be considered successful.

This does not apply to 3-D Secure authentications that are terminated by a timeout. The 3-D Secure Timeout status does not count as a completed status in which the ReqID functionality on 1cs OPS does not take effect. Submissions with identical ReqID for an open status will be processed regularly. Notice: Please note that a ReqID is only valid for 12 month, then it gets deleted at the 1cs ONline Payment.

4.3 Reversal (if a payment process has not been completed successfully)

Reversals of a payment with Bluecode QR Code payment are possible via a Server-to-Server connection. The First Cash Solution permits reversals that reference an authorisation previously made via 1cs Online Payment. If you reference a payment in a cancellation, the whole payment is cancelled. A cancellation is not possible for successful completed payment processes. To refund money to the consumer use “credit”.

To carry out a Reversal for Bluecode QR Code payment via a Server-to-Server connection please use the following URL: https://www.computop-paygate.com/reverse.aspx

5 Batch processing via the interface

Basic information about using Batch files and about their structure can be found in the Batch Manager manual. Within batch processing not alle functions are available which are usually available for the online interface.

This section describes the parameters which must be transferred within the data set (Record) for executing an Bluecode payment and information can be found within the response file about the payment status

For Batch calls there must be considered batch versions, from which optional parameters depend. All version designations starting with „2.“ pertain calls for a group of enterprises. That means within a batch file for a particular MerchantID can be transferred transactions for other merchants with a separate Sub-MID

Following table gives an overview of all batch versions that are possible for a specific action an their specialities:

ActionVersionDescription
Credit1.0 / 2.0Standard version without return of parameter Code
 1.x / 2.xwith RefNr (valid for all versions other than 1.0)

Description of the possible batch versions

The structure for a Bluecode credit within a Batch file to be submitted is as follows:

HEAD,<MerchantID>,<Date>,<Version>

Bluecode,Credit,<Amount>,<Currency>,<TransID>,(<RefNr>,)<PayID>

FOOT,<CountRecords>,<SumAmount>

Example for Master MID function:

HEAD,[Master]MerchantID,Date,2.x

Type,Action,[Slave]MID,Amount,Currency,TransID,Data (depends on Action)

FOOT,CountRecords,SumAmount

The following table describes the individual fields and values used within the data set (record) in the batch file:

6 Test data

Bluecode provides a special Sandbox-App to provide test functionality. This Sandbox-App is not available in the official Appstores, but is available here:

iOS: https://install.appcenter.ms/orgs/bluecode-organization/apps/at.secure-shopping.bluecode.sandbox-ios/distribution_groups/public

Note on iOS: When installing the sandbox app for the first time, the company app “bluesource” must be trusted once on iOS devices under “Settings> General> Profiles & device management”. Only then the sandbox app can be used on iOS

Android: https://install.appcenter.ms/orgs/bluecode-organization/apps/com.spt.bluecode.sandbox-android/distribution_groups/public

Please note:

After installation of Bluecode Sandbox-App the Bluecode has to be connected to a bank account:

  • After installation of Bluecode Sandbox-App you have to setup a PIN for the App.
  • Then click on “Connect bank account” and enter “test” in the bank search.
  • The entry “Activate a test user” is then displayed. A test account can be added by clicking on it.
  • To do this, select the first entry “Hypo Tirol”.
  • A blue code for payment is then displayed.
  • To scan a QR code with your smartphone, tap the QR symbol in the top left of the app to activate the camera.
  • The amount is then displayed on the smartphone for confirmation. You confirm this by “swiping”.

In the Bluecode Sandbox app, no “real” payments are made, they are only simulated!

The Bluecode Sandbox App also has some transaction limits (per hour / per day). In case you need to disable the transaction limits please send an email together with your Bluecode Sandbox App “Bluecode ID” to devsupport@bluecode.com.

You will find the Bluecode ID here:

7 Important notes when switching to live payments

The 1cs Online Payment System itself has a certified Bluecode implementation. However, when switching from test to production mode a merchant has to ensure:

  • Use the 1cs Online Payment System URL “Bluecode.aspx” to initiate a Bluecode payment with redirect to Bluecode page containing the QR code
  • Use the 1cs OPS URL “BluecodeS2S.aspx” to retrieve a Bluecode URL which has to be transformed into a QR code by the merchant system
  • Values for request parameter “RefNr” are unique per payment process – duplicate values will be rejected
  • Values from response parameter “TransactionID” must be printed on customer’s invoice / receipt
  • Values from response parameter “TransID” must be printed on customer’s invoice / receipt if not empty
