We need a HASP key solution, only cheaper. Basically it should have a Microprocessor (PIC) and EPROM memory (even I2C). Other solutions are welcome. The memory should be at least 256 bytes in size, but isnt really needed to be bigger than 32 KBytes.It should work as the HASP keys from eAladdin for example (or at least replicate most of their security features), LPT or USB solutions (preferably LPT).What you should offer:The complete schematic for producing the plug, parts names, etc.A Windows driver for accessing the plug (complete source code).A Linux driver for accessing the plug (optional).Some API documentation for using the plug from CC andor C#, Delphi, eventually Java.
Bid Smart - The lowest bidder doesn't always get chosen, far from it. Persuade your buyer why they should pick you - and they will.
Research - If John has paid more than $500 a contract for his last 10 project, why would you think he is interested in your $10 bid? Check up on the buyer, bid what he expects, and deliver quality to match.
Read - Please read the bid request - I cannot emphasise this enough - if you do not read the bid request then you will not be chosen, this is pretty much certain. Mention the bid request specifically in your application, and don't forget to repeat the key deliverables.
Innovate - Suggest features the bidder didn't mention, talk about future extensions to the project, and discuss whether you think his or her approach is a good idea. Show interest, intellect, and willing.
