IDV levels represent your level of identification as a VIABUY customer and determine how much you can load your card with.
The Money Laundering Regulations 2007 require banks and financial institutions, such as Crosscard S.A., to ensure that they know their customers, conduct customer identification and verification, and undertake ongoing monitoring where applicable.
There is IDV Level 1, IDV Level 2 and IDV Level3.
