B4J Question Sum Up payment management

[udg]

Hi all,
I'm a bit confused about the requirements to use a Sum Up terminal to integrate its payment features in a UI B4J app.
First I read there's a need fo a BLE 4.0 communication between PC and terminal, then I found a different page were everything seems to be based on a REST API (so httputils2 should suffice, right?) and finally I see SDKs and APIs available for iOS and Android only.

My goal is very basic. A PC acting as a cash register totals the amount due, passes that amount to the Sump Up terminal which conducts all the needed operations in order to close the financial transaction. Finally the terminal sends a message back (ok or fail) to the listening PC.
I don't need to save customer data or any other data for that matter. Just have a "gateway" to let them pay by card instead of cash (well it could be even a mix of the two but we leave this to my B4J app).

So, where's my question? It could be: anyone developed a similar solution? Anyone can suggest me the steps to take in the right direction? TIA

For anything regarding REST, yes, okhttputils2 (NOT httputils2) should do the Job fine ;-)

I could not found any windows implementation too. So you need to use an Androiddevice it seems/i fear to communicate with the Terminal.

Hi Manfred,
I fear the same. Anyway I mailed them and will post here their reply.

okhttputils: sure, it was just a typing error but I appreciate that you amended it so others won't risk to use the wrong lib.
