Applies To: LaundryCard, FasCard

Problem

When Dexter washers clear escrow, the reader re-sends funds to the machine without returning to idle.

Solution

Update reader firmware to v1.21.01+

Reason

A previous bug existed where a reader (LaundryCard and FasCard, both) would persist resending funds when Dexter controls timed out after 30 minutes. This would cause reporting issues in Dexter Live as each resend counted as a transaction. Additionally, it allowed for a reduced-cost or free start indefinitely until either a power cycle, vend completion, or machine start.
