Excellent growth figures - on EU levels the e-id volume would be 1,5bn. All public sector id-transactions are presently done by banks. This is extremely cost efficient (economy of reuse) and naturally preferred by citizens - as the tool (one-time code) is so familiar (economy of repetition and secure (economy of trust).
Difficult to understand why this public-private solution has not spread to more than some half a dozen countries (not a big source of income for banks of course - more a question of better customer service and taking responsibility for speeding up e-government. Technology vendors naturally try to sell a separate tool for every purpose - but endusers prefer familiar ones.
The e-payments are introduced in -97 and have grown steadily - much for the same economy of reuse, repetition and trust reasons - but also supported by economy of scope and scale. Plus being made in real time - cutting merchant and bank risks. EU-equivalent volume would be 2,1 billion times.
