eCash
Physically and cryptographically strong computer chip-based iButton® eCash token fits on a key ring and can virtually eliminate the frequent reissuing expense associated with smart cards. For applications requiring standardization with deployed RFID technology, a contactless iButton format is also available with the same cryptographic security embedded.
eCash Tokens
iButton eCash tokens provide a simple, highly secure way of functioning like a small change purse for one or more applications. iButton tokens eliminate the need to carry small amounts of cash for everyday transactions like mass transit, parking meters, and fleet refueling. Get Started.
RFID eCash
Like an iButton but with the convenience of contactless technology, an RF key can perform various functions for electronic purse or eCash applications. The RF key stores and can replenish cash value in a smart card's secure memory, which is protected by a SHA-1 mutual authentication engine. Many of the world's mass-transit systems now use contactless fare cards or tickets. Get Started.
