Narrative:
Over the final approach fix (VOR runway 27), swf tower told us to check our altitude due to a low altitude alert which approach control received. Our altimeters checked normal in flight and after landing. The approach was executed as published with no deviations. On the ground I talked to the tower and they told us via ground control that this 'happens all the time, and it is an internal ATC systems problem.'

Narrative: OVER THE FINAL APCH FIX (VOR RWY 27), SWF TWR TOLD US TO CHK OUR ALT DUE TO A LOW ALT ALERT WHICH APCH CTL RECEIVED. OUR ALTIMETERS CHKED NORMAL IN FLT AND AFTER LNDG. THE APCH WAS EXECUTED AS PUBLISHED WITH NO DEVIATIONS. ON THE GND I TALKED TO THE TWR AND THEY TOLD US VIA GND CTL THAT THIS 'HAPPENS ALL THE TIME, AND IT IS AN INTERNAL ATC SYSTEMS PROB.'
