What is the best business card scanner app that works with Zoho CRM ?

1.  Looking for a recommendation on what is the best app that I can use to scan a b-card and have it load into Zoho CRM ?

2.  If you have more than one b-card from a company will the app automatically add the contact under the same company?

Please advise
