## Title
Card locking

## Abstract

A chip-enabled card is detected within a card reader. The card reader locks the chip-enabled card in the card reader until an indication is received indicating that a card transaction with the chip-enabled card has ended and preventing the chip-enabled card from being removed while the chip-enabled card is locked in the card reader.

## Background
BACKGROUND
Credit card theft is a major concern worldwide. Typically, a consumer is protected from theft as is the bank that issues a credit card. That is, when illegal use of a credit card is confirmed after an investigation by the bank, the consumer's account is credited for the amount of theft. However, the bank typically debits the account of a retailer that performed the illegal transaction.
To thwart illegal credit card use, banks have started to roll out dual chip-magnetic strip cards, such cards have been deployed in Europe for several years now and are in the processes of being fully deployed to United State (U.S.) based consumers.
The magnetic card readers that read chip-enabled cards are problematic to the U.S. consumer and U.S. retailer. Typically, legacy card readers that were supposed to be used for magnetic strip reading have been upgraded to read the embedded chip. The device or host device (Self-Service Terminal (SST)) interfaces were also upgraded to instruct consumers to leave the card in the card reader for the duration of the transaction (until canceled by the consumer, approved and completed, or denied by the bank).
The embedded chip on the card has to stay in the card reader for the entirety of the transaction because the reader includes a card-specific embedded key (which may be randomly updated during a transaction with a new key by the bank during the transaction). The key is used to encrypt the transaction on a unique transaction basis. This takes more processing time and therefore the card and its embedded chip have to remain in the card reader for the duration of a given transaction.
Unfortunately, this is problematic in the U.S. and for the U.S. consumer. The upgraded card readers do not physically lock the card in place during the transaction and the U.S. consumer is condition to insert and remove their cards quickly and often ignore the new interface warnings.
This is problematic for retailers for a variety of reasons. First, even for a failed transaction the banks charge the retailer a small transaction fee, which for a large retailer can add up to a significant amount of fees (especially given the frequency of failed transactions). Second, during high consumer traffic times, failed transactions delay transaction throughput at both cashier-assisted Point-Of-Sale (POS) terminals and at SSTs. So, the problem has fairly significant ramifications for retailers.

DETAILED DESCRIPTION
FIG. 1A is a diagram of a card reader 100, according to an example embodiment. The card reader 100 is shown schematically in greatly simplified form, with only those components relevant to understanding of one or more embodiments (represented herein) being illustrated. The various components are illustrated and the arrangement of the components is presented for purposes of illustration only. It is to be noted that other arrangements with more or less components are possible without departing from the card reader locking presented herein and below.
Moreover, various components are illustrated as one or more software modules, which residing in non-transitory storage and/or hardware memory as executable instructions that when executed by one or more hardware processors perform the processing discussed herein and below.
The techniques, methods, and systems presented herein and below for card reader locking can be implemented in all, or some combination of the components shown in different hardware computing devices having one or more hardware processors.
The card reader 100 includes a display 101, one or more interfaces buttons (102 and 103), and at least one internal roller mechanism 104. The card reader 100 processes chip-enabled credit/debit cards 110 having an embedded chip 111, and a magnetic strip 112.
It is noted that the layout of the card reader 100 can be in a variety of different permutations. For example, the display 101 can be a touchscreen, the interface buttons 102 and 103 can be associated with dynamically changes options from the interface of the card reader 100 and situated adjacent to the display 101. It may also be that the card reader 100 is integrated into a Self-Service Terminal (SST) and uses the touchscreen interface of the SST and/or the keyboard of the SST. It may be also that the card reader is integrated into a Point-Of-Sale (POS) terminal.
Moreover, there can be more than two hard interface buttons 102 and 103 on the standalone card reader 100. Two buttons 102 and 103 are just illustrated to show a confirm amount button 102 and a cancel button 103; but it is noted that this can done in a variety of manners and the buttons 102 and 103 can, in some configurations, be entirely touchscreen based, such that there is no physical buttons on the card reader 100 and are present in a touchscreen of the display 101 (or any of the other possible configurations for the standalone card reader 100).
During a transaction, a customer inserts his/her card 110 into the card reader 100 in an orientation dictated by instructions posted on or near the card reader 100 or by instructions illustrated in an interface presentation presented on the display 100. Therefore, the illustration on the orientation of the card 110 inserted into the card reader 100 can vary depending on the configuration of the card reader 100 and the exact orientation in the FIG. 1A is one or many possible orientations.
The roller mechanism 104 includes a roller and is illustrated in a manner for visibility and comprehension as it is apparent that the roller mechanism 104 is not visible to the consumer and is internal to the card reader 104.
The roller mechanism 104 is also interfaced to one or more electromechanical components controlled by electronic circuitry interfaced to a motherboard having at least one hardware processor that receives sensor and signal readings from the electromechanical components and permit the hardware processor responsive to the readings to control and operate the roller mechanism 104.
During operation of the card reader 100, when a consumer inserts his/her card 110 into the card reader 100 in a designated and proper orientation, sensors indicate to the hardware processor when the card 110 is fully and properly inserted into the card reader 100 for proper reading and processing during a transaction. At this point, the hardware processor locks the roller of the roller mechanism 104, which prevents the card 110 from being manually removed by the consumer until the transaction ends (canceled by the customer through cancel button 103, completed as indicated by the terminal to which the card reader 100 is interfaced (SST or POS terminal), or denied as a form of payment for a transaction by the terminal. Once the transaction ends, the hardware processor receives that indication from either the terminal, interface, or the reader 100 and the hard processor causes the roller mechanism 104 to unlock permitting the consumer to freely remove the card 110.
In an embodiment, the roller of the roller mechanism 104 is a slip resistant roller.
In an embodiment, the motherboard and hardware processor reside within the card reader 100.
In an embodiment, the motherboard and hardware processor reside external to the card reader 100 and connected to an electronic circuit board, where the motherboard controls other devices. In this embodiment, the card reader 100 is integrated into another device, such as an SST or POS terminal.
The FIG. 1A also includes some descriptive material relevant to a card transaction, such as an indication that the card reader 100 is EMV enabled. EMV stands for Europay MasterCard® and Visa® and is a transaction processing mechanism that uses card embedded chips to unique encrypt each transaction and validate the transaction.
In an embodiment, the card reader 100 is integrated into an SST. In an embodiment, the SST is an Automated Teller Machine (ATM). In an embodiment, the SST is a kiosk.
In an embodiment, the card reader 100 is integrated into a POS terminal.
FIG. 1B is a diagram a SST 130 having an integrated card reader 100, according to an example embodiment.
FIG. 1B is shown to illustrate that the card reader 100 can be integrated into the SST 130 (non-standalone card reader 100 embodiment).
The card reader 100 detects an inserted card 110 having an embedded chip 111 fully inserted into the card reader 100 and locks the roller mechanism 104 until the transaction ends (as defined above) at which point the card reader 100 unlocks the roller mechanism 104 for the card 110 to be removed from the card reader 100.
In an embodiment, the software (executable instructions) and the hardware processor that receive the readings for the hardware processor to make a determination as to when to lock the roller mechanism 104 and when to unlock the roller mechanism are contained within the integrated card reader 100 as an independent peripheral device of the SST 120.
