android - Mobile Point of Sale (mPOS) Development -

-

i asked develop mobile pos android application read chip card data device (like square) can connected audio jack of cellphone. till have done following: (1) detected device on audio jack. (2) read data there in chip. (3) read tags data/ public keys , certificates required transaction processing. (i aware not right/illegal read user data - not going store of on device)

i know next step integrate application payment gateway.

working on this, integrated payu money (a payemt gateway) android application. directs me "form" cardholder needs fill information such name, card number, expiry date etc.

i have extracted data emv chip. unable send on form. don't want clients fill of data except pin number complete transaction.

i tried other payment gateways directly take data app (point point) haven't found yet.

now, stuck @ do ? go here ? steps follow project done ?

i wondering if headed right direction ?

all or guidance highly appreciated. thank you

k,

you may not able way. there 2 ways complete transaction online :

  1. using webform fill in data printed on credit card : card number, expiration date, cardholder name (which accessible reading card chip/magnetic track) and cvv number written behind card (which not available in chip).
  2. using pos application, complete emv dialog card in order sign , approve transaction.

it seems you're trying achieve option 1. unless manually inputs cvv code, won't able complete transaction.

however, mention of pin number implies want emv transaction (there's no pin webform based transactions). painful process, require use certified emv kernel (or couple of years code own), , certification application. not you're trying do.

last option, use square connect api, whil take care of payment processing you. unfortunately, have switch ios, since it's not supported on android.
