Software Modification for Tripod Turnstile based on RFID as Lock and Unlock Trigger

Problems

For most programmers knew that Tripod Turnstile can’t delete RFID data after visitors pass through. This is necessary so that the card has been used can not be used again. Cards can be used again when it is refilled at ticket booths. So, how it can be happend ? While the card reader can not be set to automatically remove registered RFID cards by self. One of several way is to create a software that works automatically for delete data.

How I solved the problem

Let’s see the illustration below :

(1). When ticket seller sold ticket, they tagging to RFID reader to store Mac-Id data to reader located insite Tripod turnstile, so that RFID cards has registered as legal user to passed in. (2). And then when visitors passed through from Tripod Turnstile, (3). server detect tagged RFID number and start to delete registered RFID data on Reader located inside the Tripod Turnstile.
