Payment rails are the infrastructure that enables the transfer of money between banks, financial institutions, and payment service providers. For businesses, choosing the right payment rail depends on factors like speed, cost, geography, and customer satisfaction.
NEFT (National Electronic Funds Transfer) and IMPS (Immediate Payment Service) are two common payment rails in India. While NEFT processes transactions in batches and operates during specific hours, IMPS offers real-time, 24/7 fund transfers. Lightspark is trying to move past these traditional payment rails by introducing the 'Money Grid,' a global payments network built on Bitcoin’s decentralized foundation.
The Payment Rail Landscape
Payment rails are crucial for moving money between parties, but current systems can be slow, fragmented, and costly. These inefficiencies highlight the need for more streamlined and cost-effective solutions in the financial ecosystem.
Understanding NEFT and IMPS
How NEFT Works
NEFT (National Electronic Funds Transfer) is an electronic payment system in India that processes transactions in hourly batches. The sender initiates a transfer by providing the beneficiary's details and authenticating the transaction via OTP or internet banking password. The sender's bank sends the transaction to the NEFT clearing center, which sorts and batches it with others. Settlement files are then sent to the beneficiary's bank, which credits the funds to the beneficiary's account. NEFT uses secure electronic channels and the IFSC code for branch identification, ensuring a reliable and secure transfer process.
Strengths and Limitations of NEFT
Strengths- NEFT allows both small and large transactions with no minimum or maximum transfer value, making it versatile for various needs.
- It is available 24/7, 365 days a year, ensuring users can initiate transactions at any time, including weekends and holidays.
- NEFT transactions are secure and reliable, with strong authentication mechanisms and oversight by the Reserve Bank of India.
- NEFT transactions are processed in hourly batches, which can result in delays compared to real-time systems like IMPS.
- It is not suitable for urgent payments as funds may take up to a few hours to be credited, depending on the batch timing.
- Both the sender and recipient must have accounts in NEFT-enabled banks, limiting its use if either party's bank does not participate.
How IMPS Works
IMPS (Immediate Payment Service) is an Indian electronic funds transfer system that enables instant, real-time interbank transfers 24/7. Managed by the National Payments Corporation of India (NPCI), it uses a secure infrastructure involving the IMPS Switch, message brokers, and directory services. A typical transaction involves the sender initiating a transfer via mobile banking, internet banking, or ATM, authenticating it with MPIN or OTP, and NPCI routing the request to the beneficiary's bank. Upon validation, funds are debited from the sender's account and credited to the recipient's account, with both parties receiving instant notifications.
Strengths and Limitations of IMPS
Strengths- IMPS enables instant, real-time fund transfers 24/7, including weekends and bank holidays.
- It supports multiple payment options, including mobile number & MMID, Aadhaar number, and account details, providing flexibility.
- IMPS transactions are secure, utilizing OTP verification and encrypted channels to ensure safe delivery of funds.
- IMPS is limited to domestic transfers within India and cannot be used for international transactions.
- There is a maximum transaction limit of ₹5 lakh per day, which may not be sufficient for very high-value transfers.
- IMPS transactions cannot be reversed once completed, making it essential to double-check details before initiating a transfer.
NEFT and IMPS Compared
Transaction Speed
NEFT processes transactions in hourly batches, typically taking from 30 minutes to a few hours for funds to be credited. In contrast, IMPS offers instant, real-time fund transfers 24/7, making it ideal for urgent payments. Lightspark, leveraging the Lightning Network, also provides real-time, instant money movement globally.
Fees
NEFT fees vary by bank, generally ranging from Rs. 2.5 to Rs. 50 per transaction, with some banks offering free online NEFT for savings accounts. IMPS fees also vary, typically between Rs. 2.5 to Rs. 25 per transaction. Lightspark emphasizes low-cost payments, often at a fraction of traditional costs.
Cross-Border Capabilities
NEFT allows limited cross-border transfers to Nepal under the Indo-Nepal Remittance Facility Scheme, with a cap of Rs. 2 lakhs per transaction. IMPS is restricted to domestic transfers within India. Lightspark, however, supports seamless cross-border payments across 140+ countries and 120+ currencies.
Security Protocols
NEFT transactions are secure and reliable, overseen by the Reserve Bank of India, though specific technical details are not provided. IMPS uses OTP verification and encrypted channels for secure transactions. Lightspark enhances security with Bitcoin’s decentralized foundation and multi-factor authentication methods.
Operational Hours
NEFT is available 24/7 but processes transactions in scheduled batches, which can lead to delays. IMPS operates 24/7, including weekends and holidays, ensuring instant fund transfers at any time. Lightspark also offers 24/7 payment capabilities, ensuring money can move anytime, anywhere.
How NEFT And IMPS Are Used
Salary Payments
NEFT is ideal for bulk salary payments due to its ability to handle large transactions without an upper limit. IMPS, with its ₹5 lakh cap, is less suitable for high-value payrolls. Lightspark offers real-time, low-cost global payments, making it perfect for international payrolls and reducing float.
Emergency Fund Transfers
IMPS excels in urgent situations with its instant, 24/7 availability. NEFT's batch processing can cause delays. Lightspark's real-time, always-on payments provide a superior alternative for emergencies, ensuring funds are transferred instantly across borders without hidden fees.
Vendor Payments
NEFT is suitable for scheduled vendor payments, especially for large amounts. IMPS is useful for smaller, immediate payments. Lightspark's infrastructure supports seamless, low-cost cross-border vendor payments, enhancing efficiency and reducing operational costs for businesses.
Peer-to-Peer Transfers
IMPS is preferred for quick, small-value P2P transfers due to its real-time processing. NEFT is less practical for such needs. Lightspark offers instant, secure P2P payments globally, supporting multiple currencies and reducing transaction costs, making it a versatile option for personal transfers.
