Business card scanner, maybe CardMunch? Works with LinkedIn
As far as a magnetic scanner, what are you looking for? If it is to swipe badges it won't be of much use unless you know how the badge in encoded. Most trade shows I go to (most major restaurent technology shows in the US, NRA, HITEC, FSTEC, etc.) won't give you the encoding, they want you to rent their machines.
If it is to do sales, perhaps try Square?
