we have added CVV and Zipcode security on OLO payments. 

This is available with OLO. 

We have manual upload option with QB. You need to do the mapping in Linga BO and csv file can be uploaded in QB. Automatic upload can be done using Shogo. 

This is fixed with 3.0.4 or higher versions.

We have completed the barcode based customer scanning, barcode is available with a custom olo app and only the customer can show the barcode to open the profile. This way it is secure and also we are restricting employees to add customer profiles. 

This will slow down the operation in high pace environment.
