The credit limit for secured credit cards is determined by the amount of security funds you set aside. There are limits for the security fund for Neo's secured credit cards.
Minimum security funds: $50 ($200 for World Elite® credit cards)
Maximum security funds: $10,000
You can add more security funds to increase your credit limit (to a maximum of $10,000). Currently, it's not possible to reduce the amount of security funds. If you want to withdraw your security funds, you need to pay off the balance of your card and close your credit card account.
