Greetings ,
What Casino's will ask for to Verify ones account will vary :
Usually the standard requirements will be
1. Photogenic Identification (passport , drivers licence , an Identity Card (Government issued) , and sides front and back.
(To Prove ones age and Identity)
2. A Utility Bill or If they allow an Official Letter ..Bank Statement does the trick most times.
(Proof of Address)
3. If purchases have been made they may ask for proof more than likely with credit cards they will ask
for the front and back (as advised by Val'Des Blur out those sections to take temptation away from the tempted I mean we are dealing with humans here not robots
Another example is U'kash you will be asked most times to provide a scan of the voucher , Another example if the payment was via Neteller they will request a screenshot of the account and you will show them the purchase.
For all the above if there's anything private you don't want people to see simply load the scanned image ..also with the scanned image make it 1200dpi .. load it into paint , photoshop , and whatever else takes your fancy.
Now for the editing part you know what you don't want them to see for example will leave out those purchases for xxx mags ,and etc ...you know what I mean.
Happy Gaming.
