Replaced my car's fastag

I have been using Fast Tag from Paytm Bank for the last 3 years. There are some issues with the Paytm Bank in India and because of that, they have announced to discontinue their fast tag service. For those who do not know I would like to mention and inform them that fast tag is a way to collect toll fees electronically. Every toll has a device that scans the QR for the tag and accordingly, the toll charges are deducted from the bank account. This tag needs a recharge so we need to keep some balance in there and accordingly based on the distance the charges for the toll are deducted.

Because Paytm Bank is not functional anymore it was needed to replace my existing tag with a new one and I have chosen this one which is from HDFC Bank. Banks are the ones issuing this fast tag to make the toll collection electronic and convenient because this way no need to wait and pay the cash to the person because it's all will be taken care of by automated collection.

I placed the order for a new fast tag last week and finally, I got it today which is good because I'm planning to travel this weekend and before I start I want you to have this tag replaced. If in case the toll fee is not deducted automatically or the balance is not there then they ask for double amount in the form of cash which is never a good thing to go for and this is why I avoid such bad experiences.
