I became a Pensioner at 52. Setting up an Indian Subsidiary for a French MNC IT firm at 54 helped me in continuining my play with CCs.
Even at 62-63, we got CCs from AMEX-1, AXIS-3, ICICI-3, SBI-3, PNB-2, INDUSIND-1, KOTAK-3, UBOI-1, SBM-1 - besides pre-paid ones like PepperMoney and Junio.
Absolute first timers for CC - pensioners beyond 60 - I suggest a Secured CC and start scouting for other CCs on a C2C basis.
