We need a list of companies within the US and Europe for the following:


- Apparatus, equipment and vending machine manufacturer (engineering)
- System integration
- Data cards, barcode and RFID systems
- Software program

Where can we find companies for the above mentioned components?
What website can we use which has all the companies for these products?
(We tried Google already, but hope to get more specific websites or business directories regarding this).

Any good and helpful advice would be greatly appreciated!
Thanks for your time in advance!
