Hi actually i want to develop an application for Milk shop which will

1.Use RFID to mark delivery of milk to customer. Each customer will be provided by tags and workers with RFID readers. when workers come back to shop after delivery i want to fetch delivery data in my program and store milk delivery detail in my application like who took how much milk today and who didn't n all.
2.Want to fetch all milk data analysed by Ekomilk Ultra Milk analyzer,milkana98-2a which has RS 232 port
Can java communicate to this machine which we use for analyzing milk ? I want to fetch all data from this machine to my program and save all records so eliminates manual writing stuff.
3.How much a RFID scanner will cost ? and how much for a tag ?

Please help me what i need to study?

The MakerShed catalog has a reader and several RFID tags in various forms for about $65. The output of the reader is good-old TTL serial so you would need an adapter to talk to a computer USB port.

Having the reader talk to an Arduino micro-controller is a cool option.

These RFID tags are "passive" so your sensor needs to be fairly close to the tag. Active tags that work at a distance are a lot more expensive.
