CRM for personal networking use

Hey all I regularly do a lot of networking. Both locally and nationally. I generally have nothing to sell. It is more like industry conferences and such. I may occasionally have a need to reach out to some people for business purposes, or they are just good people to keep up with. So many CRMs have uber complications, sales processes, etc. I just want an easy way to track the people I meet, record their business cards, categorize them, make some notes and maybe set a reminder to reach out to them in the future. Any recommendations on something like this?
