This small line in the LightSpeed 3.5 release notes quietly announces a long-awaited feature - PIN Debit support in LightSpeed:
Credit Card Processing: Support for PIN-debit and credit card processing via the Ingenico i6580 Titan debit terminal
This development allows retailers to offer another popular payment method to customers. In addition, the i6580 has a dramatic LCD screen and signature capture window. It will be interesting to see how LightSpeed interacts with these features!
