I think you have not completed the query itself. However you may consider these suggestions-
1) Cash incentives-you can have a systematic policy which will ease implementation;
2) For those continuously showing full attendance continuously for many years, one increment or advance increment may be considered;
3) With All the above or if no monetary incentive could be given, issue appreciation letter for every year of such attendance and pin up his/her photo at the entrance with a suitable citation;
4) Host a party or give him treat along with Sr.management;
5) If there is a laid down promotion policy-consider give such employees bonus points so that they are better placed among other eligible employees and so on.
