Currently, many aspects of electronic transactions have become digital, and may therefore be performed online using mobile devices. However, many of these possibilities have been adopted by no longer supporting legacy systemsin the newer and emerging economies, this does not create a major problem as they have few consumers using legacy systems and methods. But this lack of interoperability limits the adoption of legacy-compatible systems and method. It also restricts their adoption in other countries. In addition, the increased use of payment through such electronic transactions is increasing the frequency and amount of fraudulent transactions.

A computer-implemented electronic transaction method 400 is provided comprising: providing 270 a transaction identifier 150 to initiate an electronic transaction, the transaction identifier 150 comprising: a routing identifier 160; a serial number (174) not directly associated with the user 210; contextual information 190 comprising one or more parameters associated with the generation of the transaction identifier 150; verification information 180 comprising a value calculated deterministically using the serial number 174 and the contextual information 190. The transaction identifier 150 is conveyed to an Authenticator 600 using the routing identifier 160; who authenticates the transaction identifier 150 using the verification information 180, the serial number (174) and the contextual information 190, and allows initiation if it is considered authentic.

The authenticator has a high degree of freedom in defining the validity of the data contents. The improved transaction identifier may be adequately authenticated using data and values comprised in the improved transaction identifier itself. Optionally, additional external data or values (not comprised in the improved transaction identifier) may also be used. By using a serial number not directly associated with the user, more possibilities and more flexibility are provided to initiate electronic transactions, and in particular, electronic payment transactions.
