Implementation on Cardterus purchase limit & Pre Authorization (How to change limit when fueling)

1) There is an implementation of Cardterus purchase limit, RM500, and 160L.

So consider RM 500 and 160L as the separate limits, where the customers can set both, ( either or ) but each time they purchase they can only select one (purchase by amount or litre), and the corresponding full tank limit will be used.

Example : 

1. a) If the customer chose a full tank - Pre Authorization RM 180 WILL be deducted and returned within 3-5 days.
2. b) if the amount is chosen, eg; RM80/30L BUT the customer fueled only RM60/25L, there will be a pre-authorization amount on the paid amount which will be returned within 3-5 days. 
3. c) If the customer chooses 30L and paid RM60 and the customer fueled for RM60, there will be RM60 pre-authorization and returned within 3-5 days. 

Hint

2) To avoid pre -Authorization amount of RM180 being held, customers can change their full tank limit as shown below. This avoids the pre- Authorization implication on the amount.

Only the chosen amount will be held and returned within 3-5 days. 

Eg) Customers rather chose whereby to opt for a lesser limit such as RM 50 or to go by 30 litre instead of choosing a full tank as the option. This avoids the pre- Authorization implication on the amount.

Below is an example, 

Setel > Purchase Fuel > Select Pump >  Set Full Tank Limit (for first time) or Full Tank (for existing) > Adjust to scale > Change > Insert PIN > Pump activating > Start Fueling
