7 Ring

The "7 Ring" is a wearable payment ring from a Mumbai-based startup that uses Near Field Communication (NFC) technology to make contactless payments without a smartphone, bank card, or charging. It functions like a debit or credit card, connecting to a secure, prepaid wallet for transactions at NFC-enabled terminals and metro stations. The ring is designed to be durable, waterproof, and secure, and is currently available in India.
