(CNN) - A growing number of states are coming forward with their own plans to us so-called COVID-19 "vaccine passports".
Although there's no federal plan to implement any kind of passport system in the U.S., the issue is already raising both equity and security concerns.
COVID-19 digital vaccine passports are quickly becoming a divisive issue and raising privacy concerns.
As some state figure out how to implement them, tech giants are teaming up with health organizations to make their digital COVID pass a reality for consumers.
The vaccination credential initiative has teamed up companies including IBM, Microsoft, Salesforces and Oracle.
With the Mayo Clinic and the Commons Project, a non-profit with a vaccine passport app currently working with some airlines.
"You get your vaccination or your covid-19 test you're negative and you get your vaccination and you can download that onto your smartphone into your apple wallet or google pay and you store it in there"Dr. Ashwini Zenooz, Chief Medical Officer, Salesforce
But not everyone is on board.
While the companies say no location or medical data will be stored on the apps, that concern might raise concerns for potential users.
The vaccination credential initiative is playing a key role in developing U.S. standards and guidelines for those digital health passes.
The use of the passes is up to each community and institution to decide how to use the apps.
"I think some employers are making a decision to require vaccination and I think the EEOC issues a ruling in December that it's up to employers to make that decision."Paul Meyer, CEO, The Commons Project Foundation
While several states, including New York and Hawaii embracing the idea, others like Florida have moved to ban them.
