The concept of redeem and pay becomes melded into one. Perhaps a user with an 80 IQ might struggle.
Edit: to compare levels of confusion, what the heck is a Yoobit to the average person? Or any other name that doesn't have a word that means money. At least the possible associations of netcode to "coupon" or "enabling recipe" starts the user's mind in the direction of these netcodes have some exchange value.
Redeem and pay are examples of exchange.
The other words I thought of were "swaps", "tradables", "clicks", "zing", "loves" and "vibes" (where the latter three represent the human interaction value created on the internet). The first two are obviously exchangable assets, but they don't associate to internet (cyberspace) technologically specific exchangables. The "clicks" was the best attempt to capture a cyberspace action that associates with access to goods and services. But the problem is that it is a specific type of good and thus isn't as fungible as some thing that can be used to exchange for anything else, e.g. a coupon or in general a code.
Here I just invented another term to describe the human interaction value created on the internet:
eco-effect (or just ecoffect)
Sorry that doesn't work as well as codes. Too abstract. Difficult to spell and pronounce. More direct is:
vibe
But people just won't likely associate an abstract fact that money is a group effect with the actual exchange value they desire.
Otherwise if we don't want codes, then just bury ourselves in the sea of copycat names for money portmanteaus:
mycash
netcoin
netcash
digicoin
digicash
hashcash
etc..
