Buddy, can you spare a credit?

Thinking about currency in the Frontier....
It highly likely that the PGC credit did not shoulder aside local planetary currencies. And if that did not happen then some currency speculation must go on even during the period congruous with the 2nd sathar war.
Sure its one more level of detail that could be ignored in favor of the ubiquitous credit for simplicity and player ease but.....
A simple line on planetary briefs could be included to tell you what the local currency is and the exchange rate to the credit. In game an NPC could offer to pay the players a cool 10,000 but fail to specify that its in local currency. Just getting it exchanged could be a head ache and draw scrutiny from officials, "Just why are you carrying such large sums of money and were did you get? Dare say that we'll have to confiscate this till we can confirm you paid taxes on it and that its not profit from illegal activity. Please surrender your ID cards too."
