WO2006116772A9 - Electronic cards and methods for making same - Google Patents
If "picked off, the data can be used indistinguishably in a counterfeit transaction card. Importantly, the thickness T should not be much greater than about 30 mils so that it works properly with legacy card readers.
For example, magnetic material can be lithographically sputtered to create the broadcaster coil effect. Nevertheless, merchants in the United States and elsewhere are reluctant to invest the resources necessary to change all of their current magnetic-card transaction equipment for various reasons, including cost, inconvenience, disruption and lack of reliability.
For example, a non-rechargeable battery could serve as a primary battery and a rechargeable battery could serve as a secondary battery, or vice versa. The skimming and counterfeiting problem has been partially addressed by MagTek Incorporated with its MagnePrint technology.
Control then passes to back to operation These and other embodiments, aspects and advantages will become apparent to those of skill in the art upon a reading of the following descriptions and a study of the various figures of the drawing.
When inserting broadcaster 68 into slotit is preferable that the alignment guides closely align with the holes in broadcaster Then, in an operationthe problem is reworked in an operation and, then, control passes again to programming step Wire electrically connects a bonding pad of processor 56 with a bonding pad of PC board The standard encoding technique for the magnetic stripe on a transaction card is the F2F Aiken double frequency code where a binary zero is represented by a long magnetized zone and a binary one is represented by two magnetized zones, each one half the length of the zero - a long magnetized zone.
This method of coil production may have advantages in high- volume manufacturing situations. Once encapsulation is completed, the first phase of manufacture is completed.
A swipe emulating broadcaster as recited in claim 13 wherein said coil comprises a wire wound around said core. The exact length of these zones of magnetization is determined by how much data needs to be recorded on the magnetic stripe. The etching mahtek be accomplished with an acid which attacks the conductive layer but which is stopped by the insulating film.
Payment cards and devices with gift card, global integration, and magnetic stripe reader communication functionality. In an exemplary embodiment, the signal generator includes a processor having a digital output and a signal processing circuit which converts the digital output to the broadcaster driver signal.
Finally, the manufacturing process is completed in a third phase by an operation which performs an epoxy fill. Then, in an operationbattery is installed.
A method for creating a low-loop bonding for thin profile applications comprising: This approach will be referred to herein as an "emulator card", which is one form of an electronic card. In an operationa message is formatted which contains a block of data and the address information. While broadly adopted abroad, Smart Cards have not been extensively adopted in the U. It has been found that if the variation in pitch is too great, errors may be introduced into the dynamic magnetic field produced by the coils, resulting in improper operation of the emulator embodiment of electronic card A single strand of copper wire is wound around broadcaster core at regularly spaced intervals, e.
An electronic card 10 includes a digital processor, an electromechemical battery and a communication port.

Many transaction card applications have gone to HiCo magnetic stripes because it is much harder to accidentally erase the encoded data than on LoCo magnetic magrek. This is achieved magfek optional bus arbitrator In a further alterative embodiment, general processor 52 is interposed between secure processor 44 and electrical connectors If it is determined in operation that the assembly does not require reworking, control is passed to operationwhich concludes the process.
In another exemplary embodiment, the battery is part of a power supply including a power filter. Electronic cards, as noted above, tend to be relatively expensive compared to conventional, non-electronic, magnetic stripe cards.
In addition to a lack of security, conventional transaction cards are also quite magtke in storage capacity. In another exemplary embodiment, at least one of the plurality of coils is a track coil.
