We have a Standard Bank Veriphone Credit Card machine that communicates via a telkom line.

In their usual non-communicative way, Standard are trying to tell me that Telkom will no longer be supporting Banking card machines.

To sort this problem out, they have suggested that we "upgrade" our machine to something else.
We only need a simple credit card facility - nothing else and nothing fancy which is where Standard are trying to take us.

I have been unable to find out as to whether this situation is correct. When it comes to Telkom, anything could go, but could it be so, that the technology between Telkom and the banks is to become outdated and unsupported, given that both of these organisations usually live in the prehistoric era?

Does anybody out there, know about / have changed / have had communication regarding this scenario?
