We certainly didn't.
The problem with using that method is that it could get you arrested, as Vincent Richardson discovered.
In People v. Richardson , Richardson reportedly approached people at a Grand Central Terminal subway station and, in exchange for a fee, offered to swipe his Metrocard in order to allow them entrance. When he was later arrested, police uncovered three Metrocards "bent in a manner as to allow the holder of said cards to enter the subway system even though there [was] an insufficient fare on said cards to allow entry".
After he was convicted of "criminal possession of a forged instrument in the third degree (Penal Law § 170.20)," and "unlicensed general vending," Richardson appealed to the Appellate Term, First Department, which upheld the convictions.
The AT1 found that the Metrocards had been "'falsely alter[ed]' so as to constitute 'forged instruments' within the meaning of the forgery statute (see Penal Law §§ 170.00, , 170.10)" and that the verdict of "unlicensed general vending" had also been based on "legally sufficient evidence."
Looks like Mr. Richardson may be remaining pretty stationary for a while.
