Highlights:
* ERAD is taking 7.7% of all funds seized.
* Anywhere between 9.95 and 14.95 per each virtual terminal used to scan for the funds.
* $1000-ish per physical terminal used.
> In addition to presenting the value associated with a card, the terminal will read other card types such as credit and debit cards. While no value can be provided, the terminal will display a “card not supported” message to alert the trooper that this is not a prepaid card. The trooper can then compare the four digits displayed on the terminal with the last four digits shown on the face of the card to determine if the card has been cloned. If the last four digits on the face of the card do not match the four digits displayed on the terminal, the trooper should note the discrepancy and pursue further action in the investigation.
I'm not really sure why they compare the last 4 digits to detect a clone, that seems wrong to me. But in any case, that strongly implies that they can't seize from debit cards linked to bank accounts. They can only seize from prepaid cards.
It catches lazy counterfeiting. Stamp a whole bunch of cards with the same number and info, while the magstripe is what gets read and is the real account you're stealing from, the theory being that no-one really cares about the number printed on the card.
Some retailers do this too, ask or enter the last four of the card to make sure the imprint matches the magstripe, as if they don't it's most likely a cloned card.
