Practical EMV Relay Protection [PDF]
2022 IEEE Symposium on Security and Privacy (SP), 2022 Relay attackers can forward messages between a contactless EMV bank card and a shop reader, making it possible to wirelessly pickpocket money. To protect against this, Apple Pay requires a user's fingerprint or Face ID to authorise payments, while Mastercard and Visa have proposed protocols to stop such relay attacks.

Although electromagnetic protective relays are adequate for present requirements, the ever-increasing demand for higher speeds and greater accuracy and dependability seems likely to exceed the capabilities of relays now available. However, the trend toward electronic control circuits in other branches of electrical engineering, coupled with the recent ...

Simplicity in protective relaying
Electrical Engineering, 1946SIMPLICITY is of paramount importance when designing and laying out protective relay circuits. These circuits are called upon to operate so infrequently that they should be more reliable than the apparatus or lines they protect. Certain limiting conditions and requirements requested by circuit designers generally cause false tripping and make the ...

Reviewing American practise in the use of relay protective devices for electrical generating, transmission and distributing systems, there appears to have been no material change in the construction or commercial application of this class of apparatus in a considerable period of years.
