It is an easy process to change a FASTag account from one bank to another, you just need to follow the below mentioned steps:
1. If the customer’s Fastag is linked with the Paytm wallet, which is in turn connected with another bank, then he/she can change the bank account and recharge the wallet from the new bank account.
2. However, in case if the customer’s Fastag is linked with the Paytm bank account, then by changing the bank, he/she also needs to cancel the Paytm linked Fastag as well.
