It can be done. If someone applied for the card they just want cash. Get the pin# and sell the card.
There was a big ebt card ring busted in Florida.
The black market impact of stuff like this or people being paid under the table is the hardest to track and figure out the holes.
What happened in Florida is a different type of fraud than what we have been discussing. If you are referring to the case where a convenience store owner was buying SNAP cards at a discount and then supplying their store with them, the store owners, not the SNAP recipients, were the ones committing fraud.
But you are correct that some people sell their SNAP cards for cash. But that is different from selling portions of you monthly food stamp allowance and keeping the rest every month. That is how I understood stirs story and that has become all but impossible with the electronic debit cards.
Once you sell that card you are pretty much done. No more food stamps. You may get away with reporting it missing once, but for the most part you are done.
