Business Card Scanners: "Rank your referrals as you do your customers:
A for hot (you know a lot about the referral and the referrer introduces you)
B for warm (you know little about the referral and you can use the referrer's name).
C for cold (you know nothing about the referral, and you can't use the referrer's name).
Seek internal referrals (other departments, locations, divisions, branches and subsidiaries)."
