Plastic plugin works super... however one of my customers has been requesting the use of a keypad to enter the "pin number" at the time of submitting the transaction so this process will submit debit instead of credit.

The most important reason to ask for this function is because the number of chargebacks they have to fight every month due to "smart people" that abuse the protection programs from their banks.

Does anyone have a suggestion or experience with this issue??

The current gateways supported by Plastic (authorize.net and payflow pro) do not have support for pin based debit transactions. If you are aware of a gateway that does support this type of transaction and can send us some documentation we can offer a quote for customization.
