This talk will look at how to determine what security and privacy risks are worth accepting and the security benefits and downfalls of accepting and making payments using everything from PayPass/PayWave, EMV (Chip), Venmo, AliPay to ApplePay, Google Pay and PayPal. While the security and ease of use of payment tech has improved dramatically in the last 20 years, this talk won't explore every option. Specifically I will leave the costs and benefits of using cash and cryptocurrencies up to the viewers own imagination.
