If you are already an existing customer and upgraded to Wealth Program (welath/select) then you need to maintain the AMB with which the account was opened say e.g. 25K and not the AMB mentioned in the jpg image shared.
As for the benefits as asked by some. Think IDFC offers one of the best debit card features like enhanced limits, insurance protecton, Lounge access with companion, RSA, Golf lessons/games (Wealth variant has it, not sure about Select).
